Pleco Instruction Manual

Search Screen

When you first open Pleco, you’ll be presented with this screen:

welcome
welcome

(on a tablet, this will be paired with the definition screen in a single merged interface - also used on a phone in landscape mode)

The button at the top left corner brings up the sidebar menu, through which you can access all of Pleco’s other functions: recent search / entry history, flashcards, document reader, OCR, and the settings and Add-ons screens - see their respective manual chapters for more information on those.

The bar in the middle is the search field; tap on this to open the keyboard (see below for much more on that) and enter your search term; the list of results will appear below. Any letters / numbers entered in the search field will be displayed in bold if they’re being interpreted as a Pinyin string and in regular un-bolded text if they’re being interpreted as English.

At the top right corner is the button to switch your current search [Dictionary Group][] - this is a somewhat nuanced concept that you’ll want to read more about later, but by default it will essentially cycle between three different modes:

Dictionary Groups
Icon Function
C Chinese search; search all Chinese-to-English /-Chinese / -German / -French / etc dictionaries for the current search term; any letters / numbers entered will be interpreted as pinyin pronunciations.
E English search; search all English-to-Chinese dictionaries for the current search term; any letters / numbers entered will be interpreted as English.
[E] Full-text English search; search the definitions of all Chinese-English dictionaries for the current search term, interpreting it as English, and returns a list of matching Chinese-English dictionary entries.

See English Search for a more detailed explanation of the difference between regular and “full-text” English search, and see Chinese Search for more details on how Pleco interprets Chinese search strings and on special features that they support.

Tapping-and-holding on this button will allow you to select an individual dictionary and temporarily limit your search to only that dictionary; tapping on the button again will clear that up, as will entering a search term for which no match can be found in that dictionary. To avoid that latter type of dictionary switching, enable “sticky dict selection” for a particular dictionary in Manage Dictionaries, or set “Dict Search Order” in Settings / “Search Engine” to “Current Only.” You can also turn off the “Skip over on button tap” option for a particular dictionary in Manage Dictionaries and have it come up on a regular button tap just as C/E/[E] do.

Search Input

The default interface for entering a search into Pleco is the regular system keyboard, which looks like this:

keyboard
keyboard

After you enter a letter, Pleco checks whether what you’ve entered is still a valid English or Chinese search term; if it’s not, and if it is a valid search term in the opposite language, it will automatically switch to it for you without your having to press any buttons at all. If it does that because of a character that you enter by mistake, just backspace and it will return to the previous language.

Enable “Search clipboard on startup” under Settings / Miscellaneous to insert the contents of the clipboard into the Input Field when Pleco starts up, useful if you frequently find yourself copying in text from other applications.

Handwriting Input

Tap on the paintbrush icon brush to bring up the handwriting input screen:

hwr
hwr

To enter a Chinese character with handwriting input, simply draw it anywhere in the large gray drawing area in the center of the screen. The handwriting recognizer supports cursive and non-cursive handwriting, and is fairly tolerant of stroke order mistakes, though it tends to be more accurate if you draw the character with correct stroke order. If you’re not familiar with Chinese character stroke order, here’s a quick guide:

You can look up the stroke order for individual characters using Pleco’s stroke order add-on.

After you finish drawing each stroke, the result list at the bottom of the screen will automatically be updated with the characters that best match what you’ve drawn so far; the first match will be inserted in the search bar, highlighted so as to indicate that you haven’t finished drawing it yet. You can scroll the result list to the left to view additional results; just tap and drag it. When you see the correct character, tap on it to insert it in the search field, clear the drawing box and begin drawing a new character.

If you enable the “Show 2nd chars on tap” option under Settings / Input Methods / Handwriting Input, when you tap on a character in the result list, the results in it will be replaced by other characters that commonly follow it in words, in descending frequency order; tap on one of those characters to enter it, or simply begin drawing a new character if your desired character isn’t shown.

If the first character in the result list is the correct one, you don’t even have to tap on it; instead, simply tap inside of the drawing area with two fingers to clear it and begin entering another character. You don’t need to do any kind of stretching / dragging gesture, just make sure both fingers are touching the screen inside of the drawing box at the same time.

Tapping inside of the drawing area with two fingers when it’s empty will backspace (erasing the previous character entered); you can also backspace by tapping on the backspace button to the left of the “Done” button.

On a device with a button-equipped stylus (like a Samsung Galaxy Note), you can also clear or backspace by simply pressing the button on the stylus; note that you will generally have to hold the stylus near the screen in order for it to detect that button press.

If none of the characters in the result list are correct, tap on the backspace button to erase it and try drawing again. Alternatively, tap inside of the drawing area with two fingers twice - once to clear and once to backspace. Tap-hold on a character in the result list to quickly bring up a definition screen for that character.

Tap on the “Undo” button at the top of the screen to undo the last stroke drawn - big time-saver if you make a mistake - or tap on the “radical” button to switch to Radical Input.

See Settings / Input Methods / Handwriting Input to enable / disable support for simplified, traditional, and rare characters, and to make the handwriting recognizer take up only part of the screen instead of the entire screen.

Radical Input

Tap on the puzzle piece icon puzzle to bring up the radical input screen:

rad
rad

This is the same character lookup method employed in most printed Chinese dictionaries. Radical input is too complicated a concept to explain in detail here, but basically, you’re looking up characters by finding their common component (“radical”) - most often located at the left or top of the character - and then counting the number of strokes that appear in the character outside of the radical.

When you first open radical input, the grid in the center of the screen will display a list of all 214 standard Kangxi radicals, in order of their number of strokes. Tap on the appropriate radical and you’ll see a list of all of the characters containing that radical, again sorted by their number of strokes; each circled number indicates the number of strokes outside of the radical in the characters that follow it.

Tap on a character to enter it in the search input field. Tap on the radical selector button at the top left corner of the screen to go back to the list of radicals after you’ve selected one. Tap on the backspace button located just to the left of the Done button to delete the last character entered.

Normally, when you select a radical that’s specifically traditional or simplified (“speech,” for example), Pleco will filter the results to only display characters from the same character set. If you prefer that it display characters from both sets, go into Settings / Input Methods / Radical Input and un-check the “Character set filter” box. Also on that screen, check “Include Rare” if you want to include characters in the radical table that aren’t covered by any of your installed dictionaries.

Chinese Search

Pinyin Search

To search for a Chinese word in Pinyin, simply enter the letters in each syllable. You can optionally indicate a syllable’s tone (and thus narrow down the search results) by inserting a number at the end of the syllable; if you’re not familiar with Mandarin tone numbering, here’s a quick guide:

Tone Number Table
Number Example Description
1 Flat Tone
2 Rising Tone
3 Falling-Rising Tone
4 Falling Tone
5 ma Neutral Tone

So for 你好 nǐhaǒ, both syllables of which are falling-rising tones, you’d enter “ni3hao3”. You can also enter Pinyin without tones or any spaces between them, like “nihao” - in that case, Pleco will match any word with those syllables regardless of their tones.

To enter an umlaut (ü, as in nü or lü), enter a ‘v’; on some keyboards you can also tap-and-hold on the ‘u’ key to enter an actual ‘ü’.

By default, Pinyin searches without tones return all matches that start with the letters you entered; “jihu” for example would return not only “ji1hu1” but also “ji1hua4” and “ji2huan4.” This lets you see results for many searches without actually having to type in the entire word.

There’s no need to separate ambiguous syllables like “xian” versus “xi’an” or “chang’an” versus “changan” either - Pleco searches for both possibilities in those cases. You can change this and make it match syllables strictly by disabling “Flexible syllable splits” in Settings / Search Engine.

Pinyin search results are normally sorted by frequency, but if you prefer that they be sorted by their raw Pinyin, turn on “Sort Chinese by Pinyin” in Settings / Search Engine.

Zhuyin / BoPoMoFo Search

While we don’t include a keyboard for it, our search engine is fully capable of processing input in Zhuyin / BoPoMoFo, so if you download an appropriate keyboard from Google Play or your favorite third-party Android app store, the characters you enter should be parsed correctly.

Character Search

To search for a Chinese word using characters, simply enter those characters using our handwriting or radical input methods or a suitable system keyboard like Google Pinyin IME.

You can use simplified or traditional characters; Pleco will match both regardless of which character set it’s currently configured to display. When you enter a character search for which no dictionary entry is available, Pleco will try to break down the search into smaller words / characters and show you results for those.

Mixed Pinyin / Character Search

You can also search for a Chinese word using a mix of characters and Pinyin. To use this search option, simply enter a character followed by a Pinyin syllable, or a Pinyin syllable followed by a character; for example, you could look up 你好 by entering “你hao” or “ni好”. This works just as quickly as a character-only or Pinyin-only search, and can save a lot of time if you’re looking up a word where you recognize (and know the Pinyin for) one character but aren’t sure about another. And as with regular Pinyin and character searches, you use traditional or simplified characters and can enter Pinyin with or without tones.

In the interest of keeping our search indexes small, you can only mix characters and Pinyin in the first three character positions of a word - i.e., you can enter a character followed by one or more Pinyin syllables, or even a character, a Pinyin syllable, and several more characters, but you cannot enter a character, a Pinyin syllable, another character, and another Pinyin syllable. (or the opposite, Pinyin/character/Pinyin/character)

Mixed Pinyin/character searches use the same indexing system as all-Pinyin or all-character searches, and so should finish just as quickly as those searches do.

Wildcard Search

Pleco supports two kinds of wildcard searches, single-character and multi-character.

The single-character wildcard is “?” - enter a ? in place of a single character or Pinyin syllable to search for words with any character / syllable in that position. So, for example, you could look up all words with 不 as their second character by entering “?不” as your search, or all words with the form 不…不… by entering “不?不”. With Pinyin searches, the ?replaces an entire syllable, and not an individual letter; “qin?yu” for example would search for words with the first syllable “qin” and third syllable “yu”, so “qing1chu1yu2lan2” would not be one of the resulting matches since “qing” wouldn’t match the first syllable.

The multi-character wildcard is “*” - enter a * in place of anywhere from 0–3 characters/syllables. So entering “*不” would return any entry in which 不 was the first, second, third, or fourth character, and entering “*yu2” would return any word in which yu2 was the first, second, third, or fourth syllable. You can combine the * with the ? symbol, so if you wanted to look for all words where 不 was the second character or later, you could do this using the query ?*不 (or *?不).

Single Character / Syllable Search

Searches for single characters or single Pinyin syllables work almost exactly like regular character and pinyin searches, but with one key exception: instead of listing every word beginning with a particular character or syllable, we just list the single characters that match the search term you entered. We do this for performance reasons - listing every single word that starts with a common character would cause an annoying lag in returning search results, and with a common syllable like “shi” you could end up waiting several seconds or more, all for a list that would likely be much too long to be useful anyway.

So instead, once you’ve found the character you’re looking for we offer a bunch of other ways to narrow it down to a particular word beginning with that character:

Cantonese Search

Icon Function
CAN If you turn on the “Enable Cantonese Search” option in Settings / Language, Pleco will also accept search inputs in Jyutping- or Yale- romanized Cantonese. This is done through a separate [dictionary group][Dictionary Group] with the icon abbreviation “CAN”; with Cantonese search enabled, that group will become accessible just like the various C and E ones. With search strings that are ambiguous / could be interpreted as valid Pinyin or Cantonese, simply tap on that icon until you get to that “CAN” option.

Flashcard Priority Search

This is slow and slightly experimental, but if you prefix a Chinese-English search in Pleco with a ‘!’ character, entries that appear in flashcards will sorted to the top of the result list; this is particularly useful if you want to find a list of flashcards containing a particular word. (we plan to expand on this function greatly in future releases) Entries in your currently selected default flashcard category will come up before other entries in flashcards, so you can use this specifically as a category filter too.

Full-text Search

Chinese “full-text” searches allow you to search all of our installed dictionaries for entries containing a particular sequence of one or more Chinese characters in their definitions. With the addition of our new example sentence search feature in Pleco 3.0, this has gotten somewhat less useful than it used to be, but it’s still available; simply enter a # before your Chinese-character search term to perform a full-text search. You’ll see potentially two new icon modes this way:

Icon Function
[C] Full-text Chinese search of English-to-Chinese dictionaries (return English words whose definitions contain a particular Chinese word)
[CC] Full-text Chinese search of Chinese-to-English dictionaries (return Chinese words whose definitions a particular Chinese word)

If you turn on “Integrate C-E fulltext” in Settings / Search Engine and turn off “Full-text search only” in Manage Dictionary Groups / Chinese / “Full-text, Eng dicts”, that will cause the [C] option to show up along with the other three options on a regular dictionary switch button tap. (if you’re still unclear on what “full-text” means, there’s a more detailed explanation in the English search section below)

Full-text filtering

You can combine any of the Chinese search options with a full-text search by entering your Chinese search term (in Pinyin/Zhuyin/Jyutping/Yale or characters), followed by a #, followed by an English term to filter on. So “gao#tall” for example would return every entry pronounced “gao” that contains “tall” in its definition.

English Search

English searches in Pleco are very straightforward - just enter a word and Pleco will show you the closest possible match. Searches are case- and punctuation-insensitive, and ignore special characters as well; no distinction is made between an e and an é in English-to-Chinese searches. Full-text searches (see below) also ignore regional spelling variations, so “color” will also match “colour” and vice versa.

Regular versus Full-text

By default, we support two different search modes for English, regular and “full-text.” You can switch between them by tapping on the dictionary group button, though if you haven’t installed an English-to-Chinese dictionary yet the only option supported will be “full-text.”

A regular English search searches English-to-Chinese dictionaries (dictionaries that specifically provide a bunch of Chinese translations for an English word) and returns matching entries from them - “hel” would give you a list beginning with “held” and “helical” and “helicopter” and you’d tap on one of those to get a list of Chinese translations for it from your installed English-to-Chinese dictionaries.

On the other hand, a full-text search searches the definitions of Chinese-to-English dictionaries (dictionaries that provide English translations for a Chinese word) and returns a list of entries whose definitions contain the exact search term that you entered. So for example a search for “hello” in this mode would yield a list of Chinese-English dictionary entries for words like 喂 and 你好. This has the advantage of slightly faster access to specific Chinese words and their translations / examples / etc, plus, since our basic free app ships with several Chinese-to-English but no free English-to-Chinese dictionaries, it’s the only way to do an English search in that, but even though we try to sort the results intelligently by frequency, it will not give you quite the same quality of matches as a curated list of words from a dedicated English-to-Chinese dictionary.

If you do have an English-Chinese dictionary installed and it contains a match for the word you entered, you can actually get the same results you would get from a full-text search without having to switch to a full-text search; simply tap on that result, then tap on the WORDS tab in the definition screen and you’ll see a list of Chinese-English entries containing that word in their definitions there. If you prefer that the dictionary group button not switch into full-text mode when you tap on it, turn off “Integrate E-C fulltext” in Settings / Search Engine and turn on “Full-text search only” in Manage Dictionary Groups / English / “Full-text, Chn dicts.”

English-Chinese Full-text Search

Icon Function
[EE] If for whatever reason you’d like to perform an English full-text search in your English-to-Chinese dictionaries, enter a # before your search term as you would for a Chinese full-text search; the icon EE will indicate that that’s what you’re doing. You can also use this for an English full-text search in Englisht-to-Chinese dictionaries if you’ve otherwise disabled those using the instructions above.

Search Results

A typical entry in the list of search results will look like this:

result
result

The text is mostly self-explanatory - first line consists of the headword followed by Pinyin, second line is the first line of the definition. (English-Chinese results are the same but without the Pinyin) If this is a full-text search, instead of the first line of the definition, you’ll see the portion of the definition that contains your search term, with the search term itself highlighted. If you’ve enabled Cantonese display, the Cantonese romanization for the word will appear in curly brackets {} after the Pinyin.

Characters in the headword are colored based on their (Mandarin) tone, as an aid to memorization; you can change the color associated with each tone or turn this feature off altogether in Settings / Colors.

The two icons on the right give you two very useful pieces of information about this result:

Icon Function
PLC Dictionary; the highest-ranked dictionary in Manage Dictionaries that supplied a result for this word. (the definition in this search result will be taken from that dictionary)
[+] Flashcard status; whether or not this card is included in your flashcard / bookmark database. As in the definition screen, you’ll see a + surrounded by a dotted box if the word is already in flashcards but is not included in your current default flashcard category, or by a solid box if it’s in flashcards and included in that category; however, unlike in that screen, you won’t see any icon here at all if the word is not currently in your flashcard database.

You can customize the font sizes used here in Settings / Fonts, and can customize the arrangement of text (whether or not headword + Pinyin are on the same line, how many lines of definition, etc) in Settings / Search Screen / List layout. There’s also a “show flash status in list” option on that screen which you can disable if you find the icons distracting. (also provides a modest performance boost, since we don’t need to check the database to see if a word is included before we display it)

Tap-hold Menu

Tapping-and-holding on a search result item will bring up a popup menu with a list of helpful options:

tapholditem
tapholditem

Multi-character Breakdowns

If you enter an all-Chinese-character search for which no exact match is available, Pleco will instead attempt to break down the text you’ve entered into smaller words and bring up results for those:

hyn
hyn

Each section of the result list has a header telling you what portion of your search it applies to. If you’ve created a user dictionary, you’ll also see an option at the top of the list to add a new user dictionary entry based on this word. In Settings / Search Screen there’s an “Unknown Search” option you can use to hide this new entry prompt or to replace it with a prompt to create a new flashcard.

Sort Order

Chinese-English entries in search results (including those from full-text searches) are sorted by frequency, with the most common matching words first. In full-text searches, we also factor in the location in the entry - an entry that contains the matching word in the definition will rank higher than one that only contains it in an example sentence - and the number of dictionaries in which this word’s entry contains the search term.

If you prefer to ignore frequency and sort results purely by Pinyin, turn on “Sort Chinese by Pinyin” in Settings / Search Engine. However, in general we recommend that if you’re looking for a particular Pinyin syllable you simply enter that syllable, with its tone number if you want to further narrow it down by that. Searching for “shi4” will get you a nice frequency-sorted list of characters with that exact pronunciation, while searching for “shi” and scrolling down will take longer and give you results that aren’t necessarily frequency-sorted when you get there. Mixed Pinyin/Character Search can also be helpful in some cases like this.

In English-Chinese dictionaries, results are sorted in straight alphabetical order.

Definition Screen

Tap on a word in the search result list to bring up this screen:

dict
dict

The top of this screen lists the word itself, along with (if it’s Chinese) its Pinyin pronunciation. Tap on the audio button next to the pronunciation to hear the word spoken. If you find this button hard to reach, you can put an audio button at the bottom right corner of the screen via Settings / Definition Screen / Floating Button.

As in the search result list, characters in the headword are colored based on their (Mandarin) tone; you can change the color associated with each tone or turn this feature off altogether in Settings / Colors.

In Settings / Language there are options to replace the Pinyin with Zhuyin and to add Cantonese; there’s also an option to prefer traditional characters (so that they’ll appear first here / in place of simplified in other places like example sentences), and a “Headword Mode” option to reconfigure the arrangement of simplified and traditional characters in brackets (remove one of them, or disable the feature that replaces identical characters in brackets with -es). Settings / Fonts has options to adjust font sizes or to select alternate English and/or Chinese fonts.

At the top of the screen are up and down buttons to scroll to the next / previous search results; Pleco will retain its current tab when you scroll through results this way, so if (for example) you want to rapidly review the stroke order for every character in a list of search results they’re a very convenient way to do that.

Also at the top of the screen is a + button to add the current word to flashcards / bookmarks; by default, this will base that flashcard / bookmark on the first dictionary definition listed under DICT. That button will be surrounded by a dotted box if the word is already in flashcards but is not included in your current default flashcard category, or by a solid box if it’s in flashcards and included in that category. If you find this button hard to reach, you can put a flashcard button at the bottom right corner of the screen via Settings / Definition Screen / Floating Button.

If you’ve created a user dictionary, you’ll also see an edit icon in the top toolbar - this will edit the current user dictionary entry for this word if you have one, or create a new entry for it (pre-populated with the same headword / pinyin) if you don’t.

While the button at the top left corner of this screen will take you back to the main search screen instead of bringing up the sidebar menu, you can still access that menu by swiping your finger out from the left edge of that screen.

Below the header you’ll see tab buttons for several different sections with more information on the word:

The basic idea here is “relationships” - each tab lists every member of a particular type of item that’s related to your current word, grouped by the particular relationship they have to it, and following “DICT,” the tabs are ranked in order from the smallest (single stroke) to the largest (entire sentence) type of item.

You can navigate between tabs by tapping on them or by swiping the screen right-to-left; in Settings / Definition Screen there’s an option to reorder the tabs for more efficient access to your favorite screens.

DICT

The first tab you’ll be greeted with is DICT, showing you a list of all of the matching dictionary definitions for your selected word:

defn
defn

Each dictionary’s definitions are headed by an empty line with an abbreviation for that dictionary on the right hand side; dictionaries are sorted in whatever order they appear in Manage Dictionaries. Tap on the dictionary abbreviation to hide / show that dictionary’s definition. This selection is sticky / persistent when you navigate to a different dictionary entry, though Pleco will automatically show the top dictionary’s definition if no other dictionary is available or if all other dictionaries are hidden; you can adjust that behavior in Settings / Definition screen / Dict hiding.

Tap-and-hold on a dictionary abbreviation button to bring up this handy options menu:

If you enable “+ button for each entry” in Settings / Definition Screen, an add-to-flashcards + button will appear next to each entry as well; they’ll also appear in between entries in cases where more than one entry is included from the same dictionary (if a dictionary happens to have split its coverage of a particular word into multiple entries).

Dictionary icons from user-created dictionaries will also have an edit button next to them; tap on that to edit the entry.

If you’ve purchased our Mandarin Text-to-Speech add-on, you’ll see an audio button next to each dictionary example sentence; tap on that button to hear the example read out loud (with a highlight following along as it does).
If you find the Pinyin pronunciation in example sentences annoying / superfluous, you can hide it in Settings / Language / “Hide example pronunciation.”

As in most parts of Pleco, you can tap on any character anywhere in a dictionary entry to pull up a popup with its definition.

At the bottom of DICT for a single-character entry, you’ll see a special dictionary listed with the abbreviation UNI; this is actually not a dictionary per se but rather a database of useful character information - radicals (“RSKangXi”), grade levels, alternate pronunciations, references in other famous printed dictionaries, input codes for Chinese IMEs, etc. See the Unihan section of the manual for a complete list of fields with explanations. Tap on the settings button next to UNI to configure which specific pieces of information are displayed and in what order; some of them may require the download of an Extended version of the database, which Pleco will offer to do automatically if you try to add one of them.

If you enable the “Show Dict Slider” option in Settings / Definition Screen, a slider bar will appear below the list of dictionary entries to allow you to efficiently jump between them - simply tap or drag your finger over to the desired dictionary and the definition box will scroll to it.

STROKE

If you’ve purchased our Stroke Order Diagrams add-on, you’ll see an additional “STROKE” tab at the top of the screen; tap on that tab to bring up a stroke order diagram:

stroke
stroke

This screen lets you review the correct stroke order for all of the characters in the current word; swipe up/down to move between them. Each character’s stroke count is shown at the top right corner of the diagram.

Tap on the Play button in the bottom toolbar to view an animation of the character’s stroke order. While animating, the Play button will be replaced by a Pause button - tap on that to stop playback. Tap on the Back and Forward buttons to the left/right of the Play button to step through the character one stroke at a time, or tap on the Start and End buttons at the left / right edges of the toolbar to go to the first / last strokes.

You can change the speed of the stroke animation, remove the outline version of the character that appears by default around the strokes, or configure strokes to fade / get lighter depending on their position in the stroke order through the Stroke Order page in Settings / Definition Screen.

CHARS

The CHARS tab links you to single Chinese characters related to your current character or word.

chars
chars

Tap on any character to bring up a separate definition screen for that character. The scroll buttons at the top right corner of that definition screen will scroll you through the original list from CHARS, so if you want to go through all of the characters in a word one after another this is an easy way to do that.

Section headers both in this screen and in WORDS are collapsible - simply tap on one of them to hide the items under it.

There are a couple of types of character relationship that can appear here:

For a single Chinese character:

For a multi character Chinese word:

WORDS

The WORDS tab links you to other Chinese words related to your current character / word.

words
words

Tap on any word to bring up a separate definition screen for that word. As with CHARS, the scroll buttons will let you traverse the entire list without having to go back and tap on a different result.

There are a couple of types of word relationship that can appear here:

For an English word:

For a Chinese word:

The words containing section is normally sorted by frequency, but in Settings / Definition Screen you can turn off “sort words by frequency” to have it sorted by Pinyin instead.

SENTS

The SENTS tab provides you a cross-dictionary search of all example sentences containing your current word, rather than just the examples in that word’s dictionary entries:

sents
sents

As in DICT, these are separated by the dictionary they come from (sorted in Manage Dictionaries order, first for the current language - Chinese-English or English-Chinese - and then for the opposite), with a collapsible header for that dictionary on top. Also as in DICT, you can tap on the icon next to any example to hear it read out loud, and can tap on any character in any example to bring up a popup definition.

By default, the number of examples is limited to 1000; you can raise or remove this limit in Settings / Definition Screen.

Popup Definition

One of Pleco’s most useful features is that nearly anywhere in our software - be it a flashcard or a reader document or an example sentence or a dictionary definition - you can tap on any Chinese character to bring up a popup definition in a bubble, like this:

popdefn
popdefn

This is an abbreviated form of a single definition from the [definition screen][DICTS], with example sentences removed. Since it’s such a tight space, rather than having you scroll through every definition we have you flip through them with buttons - tap on the dictionary abbreviation at the top right corner to switch to a different dictionary, and tap on the scroll buttons below it (if any) to scroll through alternate definitions for this character / word from that same dictionary.

The selection will initially extend to the longest possible word beginning at your current character position; you can drag the handles at the start / end of the selection or tap on the arrow buttons at the bottom of the screen to adjust it. The |⬅︎ button shrinks the selection by 1 character, the |➡︎ button expands it by one character, the ⬅︎ button moves to the previous word and the ➡︎ button moves to the next word. Settings / Popup Definition / Flip buttons left-to-right will let you reverse the order of these arrows, convenient for left-handed users.

At the top of the screen are 5 “action buttons” to do various things with the current selection:

Icons
Icon Function
go Bring up a separate Definition Screen with the current selection (grayed out if there are no dictionary entries that match it)
search Jump to the main dictionary Search Screen and search for the current selection.
add Add the current selection to flashcards / bookmarks; if there’s no dictionary entry matching the selection, you’ll get a screen allowing you to create a custom card instead.
audio Play audio for the current selection (if available).
clip Copy the current selection to the clipboard.

Another “megaphone” button will appear here in the document reader to begin reading from the current selection with text-to-speech - see the reader manual for more on that.

Merged Search + Definition Interface

On a tablet, instead of separate search and definition screens, you’ll see a single combined screen like this:

combined
combined

This also what you’ll see on a phone in landscape orientation. The functions are basically the same as in the separate search and definition interfaces.

The “Embed Definition” option in Settings / Search Screen will let you enable / disable this merged search interface, customize which side of the screen the list appears on, and make the list larger / definition smaller.

History

Tap on the “History” item in the sidebar to bring up a comprehensive list of recent searches and recently viewed dictionary entries:

hist
hist

Choose “Clear”from the top-right menu to clear the current history type, or tap “Dump to Flashcards” to dump it to a flashcard or bookmark list.

Dict/Reader/OCR

The first three tabs - Dict, Reader, and (if you’ve purchased our OCR add-on) OCR - each offer a list of dictionary entries recently viewed through those three interfaces, grouped by the time you viewed them.

An entry is added to the Dict history when you tap on it in the search result list to view its definition; on a tablet, we also add the first entry in the results (visible as you type your search) if 3 seconds elapse without your entering another search character / switching to a different entry.

The Reader history lists every entry that came up after an initial tap on a word to bring up the Popup Definition screen, along with any word that you cared enough about to tap on the > button to bring it up in a separate screen. By default, it does not add any word that you get to by tapping on the arrow buttons - turn on “Save on selection change” in Settings / Popup Definition to have it do that.

The OCR history lists every word that the OCR “locks on” to, which means a lot of words - this is intentional so that if a word flickers in briefly and then disappears you can still go back and find it, but it also means that if you’re a heavy OCR user, you likely won’t see many history entries that are more that a few days old.

Tap on an item in any of these sections to bring it up in a Definition Screen.

The Search tab lists all of your recently entered search terms. Searches performed on the way to typing a full word (nih -> niha -> nihao for example) are overwritten so that you only end up with the final word. Tap on a search to jump back to the Search Screen and search for it again.

Cards

This tab lists your recently created flashcards. For performance reasons, it does not list all of them going back to the beginning - only the most recently created 1000; go to Organize Cards to view your entire collection. Tap on a card / bookmark to bring it up in the Card Info screen.

Manage Dictionaries

The Manage Dictionaries screen lets you configure the priority order in which dictionaries are searched and in which they appear in the definition screen; it also lets you enable / disable them in dictionary searches:

manage dicts
manage dicts

Tap on the Chinese and English buttons at the bottom of the screen to switch between managing Chinese-to-English and English-to-Chinese dictionaries.

To change the search order,simply drag the dictionaries into whatever order you like.

An additional Add User button will appear here if you’ve purchased the Flashcard System add-on module and hence have access to Pleco’s user-created dictionary system; tap on that button to create a user dictionary (or to reinstall one from a database file).

Details

Tap on the name of a dictionary to view / change some configuration settings specific to that dictionary:

managesingledict
managesingledict

Browse

Tap “Browse all dictionary entries” to view a list of every entry in the dictionary; mostly helpful in user dictionaries (where there’s the additional option to edit / delete entries), but also fun if you feel like reproducing the experience of flipping randomly through a paper dictionary.
Settings

The options in “Settings” work as follows:

In general, we don’t recommend changing any of these unless you have a specific reason to do so.

Icon

“Icon Abbreviation” lets you change the letters (up to three) that appear in the dictionary’s icon; this is useful if you have difficulty quickly telling the difference between certain letters or remembering the abbreviation for a particular dictionary. “Reset to default abbreviation” will restore the dictionary’s default abbreviation. (this option will probably go away in a future release, so please don’t get too attached to it)

Information

Short Name, Menu Name, Full Name, Copyright, and Number of Entries are all exactly what they sound like.

Operations

Additional options will appear at the bottom of this screen for user dictionaries; see below for more on those.

Browse Entries

Tap-hold on a search result in the Search Screen or a dictionary abbreviation icon in the Definition Screen and select “Browse Dictionary,” or tap on the “Browse all dictionary entries” item for a particular dictionary in Manage Dictionaries, to bring up this screen:

browse
browse

This will let you browse every entry in the dictionary in their original sort order (usually first syllable, then first character, then remaining syllables, then remaining characters, just as in most printed Chinese dictionaries).
Tap on any entry to bring it up in a Definition Screen. For a user dictionary, you’ll see an additional Edit Entries button at the top right corner of the screen - you can easily select and delete individual items through that screen.

Manage Dictionary Groups

managegroups
managegroups

Pleco’s default behavior is to search all of your installed dictionaries that are compatible with a particular search type (Chinese, regular English or full-text English) and return a collated list of results from all of them. You can also search individual dictionaries by tap-holding on the button at the top right corner of the search screen and selecting them, or by disabling the “Skip over on button tap” option for a specific dictionary in Manage Dictionaries.

Dictionary groups provide a third option: you can search some of your dictionaries and return a sorted / collated list of matches from those, but exclude results from other dictionaries. This can be useful if you have more than one dictionary that you like to search for Classical Chinese or Traditional Chinese Medicine words, for example, but you don’t want to bother with extraneous results from dictionaries that don’t cover those. It can also be useful if you want to search every dictionary but with a different priority order from what’s configured in Manage Dicts.

Technically, all of our default multi-dictionary searches are done in dictionary groups - Pleco has seven special built-in groups that search all of your dictionaries for a particular language pair, in whatever priority order you’ve configured in Manage Dictionaries. You can’t change the composition of these built-in groups, but you can lower their priority or disable them altogether in favor of your own. The seven groups are:

Chinese

English

Tap on the Chinese and English buttons at the bottom of the screen to switch between managing Chinese and English dictionary groups.

Tap / drag the handles at the right of each dictionary group to change their position in the search order; dictionary groups always come up before single dictionaries.

Tap on “New Group” to create a new dictionary group; it will be created for your currently selected language (Chinese or English) and a popup will appear asking you to select the specific type of search to perform. Each option here is equivalent to one of the built-in groups, the only difference is that the custom group you create can have a subset of all of the available dictionaries (and in a different order):

Group Types
Group Type Built-in Equivalent
Chinese
Regular Search (Mandarin) All Chinese Dicts
Regular Search (Cantonese) All Cantonese Dicts
Full-text Search (English Dicts) Full-text, Eng dicts
Full-text Search (Chinese Dicts) Full-text, Chn dicts
English
Regular Search All English Dicts
Full-text Search (English Dicts) Full-text, Eng dicts
Full-text Search (Chinese Dicts) Full-text, Chn dicts

Tap on the name of a dictionary group to view / change its settings in more detail:

Most of the settings are the same as their equivalents in Manage Dictionaries:

Information

Operations

User Dictionaries

Pleco includes a powerful system for creating, editing, and importing new dictionary entries right on your device; you can add a new dictionary entry and have it immediately start coming up in searches / the document reader / etc.

Because they share a lot of the same code, the Pleco user dictionary system is closely integrated with the flashcard system, and is only accessible if you’ve purchased the Flashcard System add-on; otherwise, the following options will be hidden and inaccessible.

Database Management

All of the following functions are done through the Manage Dictionaries screen, which is accessible through Settings in the sidebar menu.

Creating a New User Dictionary

To create a new user dictionary, just go into Manage Dictionaries and tap on the “Add User” button at the bottom of the screen. Then, tap on “Create New” to create a brand new user dictionary, enter a name for it, and tap “Done” to finish creating the dictionary. Make sure you’ve selected the correct language for your dictionary at the bottom of the screen before tapping on that button; “Chinese” for a Chinese-to-English dictionary or “English” for an English-to-Chinese one.

To alter the new dictionary’s icon abbreviation or change its name / copyright, tap on the newly-created dictionary in the list of dictionaries, then tap on the field next to “Abbreviation” to edit the abbreviation or tap on one of the “Short Name” / “Full Name” / “Menu Name” / “Copyright” boxes to edit the contents of those.

Installing an Old User Dictionary

To install a previously backed-up user dictionary, tap on that same “Add User” button at the bottom of the Manage Dicts screen, then tap on “Load Existing” and select your dictionary database file from the file list.

With old dictionaries transferred over from Palm OS or Windows Mobile, the database format may need to be upgraded to optimize performance; see below for how to do that.

Locking / Unlocking

Locking a user dictionary prevents further editing, useful for dictionaries you’re distributing publicly, and also speeds up scrolling / browsing through the dictionary a bit due to some extra indexes it generates.

To lock a user dictionary database, go into Manage Dictionaries, tap on the dictionary’s name, scroll down and tap on “Lock Database.” (this may take a minute or two with larger dictionaries) Tap on “Unlock Database” to lock it again.

Upgrading Format

Dictionaries created with versions of Pleco on Palm OS or Windows Mobile prior to 2.0.4 need to be updated to the latest version of our database format to perform well; they’re not usable at all otherwise.

To upgrade a user dictionary database, go into Manage Dictionaries, tap on its name, scroll down and tap on “Upgrade Format.” (this may take several minutes or more with larger dictionaries) The option won’t appear if the dictionary has already been upgraded.

Importing Entries from a Text File

To import lots of entries at once, e.g. from an existing dictionary data file or wordlist found on the internet, use the Import Entries function to import them from a text file. Create a new user dictionary database (if you don’t already have one) in Manage Dictionaries, tap on its name, scroll down and tap on “Import Entries” to bring up the import screen:

userimport
userimport

Tap on Choose File and select a text file to import entries from. The format is exactly the same as in flashcard import files, i.e., headwordPinyindefinition for Chinese-to-English dictionaries or headworddefinition for English-to-Chinese, except without the // category headers.

Choose the text encoding for the file - the system used to encode Chinese characters in it - in Text Encoding; UTF–8 is the most common encoding, and files that use other encodings will likely tell you so on the website that you download them from.

Undo Last Import removes any dictionary entries added during the previous import - this includes flashcard imports too if you import flashcards with the “Store in user dict” option enabled.

Tap on Begin Import to start importing dictionary entries - this may take a while, and you won’t be able to do anything else with Pleco while it’s running, so we recommend waiting to do it until you’ve got a lot of time on your hands.

Exporting Entries to a Text File

You can export the entire contents of a user dictionary to a text file using the Export Entries command. Tap on the dictionary’s name in Manage Dictionaries, scroll down and tap on “Export Entries” to bring up the export screen.

userexport
userexport

Choose a Text Encoding - UTF–8 is the most widely used and in most cases the best choice - then tap on Begin Export to enter a file name and start exporting the file. (this is usually much faster than an import)

Backing Up / Sharing

To back up a user dictionary database - much faster than exporting / importing it - tap on the dictionary’s name in Manage Dictionaries, scroll down and tap on “Backup Database.” Enter a name for your new database and tap “Save” to begin the backup.

To load this file back into Pleco, add it through the Add User / Load Existing command.

Full-text Indexing

By default, user dictionary definitions are not included in full-text searches; however, you can add a full-text index for English searches in Manage Dictionaries / “Add Full-text Index.” Tap “Optimize Full-text Index” to improve performance slightly after adding / deleting a lot of entries, tap “Rebuild Full-text Index” if you encounter a lot of bugs / problems and want to rebuild the index entirely, or tap “Remove Full-text Index” to disable and remove the full-text index so that the dictionary is no longer included in full-text English searches.

Entry Management

Adding Entries

To add a new user dictionary entry, create a user dictionary (if you haven’t already), then enter a Chinese search term in the Search Screen. If a dictionary entry does not exist for that word, you’ll see an option at the top of the result list to create a new user dictionary entry; if one does exist, tap on it, then tap on the edit button at the top of the screen to create a user dictionary entry for it (or edit the existing one if it already exists). You can also create a new user dictionary entry through the “New Entry” button in the dictionary’s Browse Entries screen. In either case you’ll end up with the Edit Entry Screen:

editentry
editentry

Tap on one of the edit fields (Simplified Character Headword / Traditional Character Headword / Pinyin Pronunciation / Definition) to edit the text of that part of the entry. Tap on Dictionary to change which dictionary the new entry will be created in (if you have more than one user dictionary installed), or tap Switch Language to change which language pair the new entry will use (English-Chinese or Chinese-English). For the headword sections, if you’ve purchased our handwriting add-on you can tap on the bar at the top of the screen to toggle between handwriting and keyboard input.

If you’re creating an entry with a mismatched number of characters and Pinyin syllables and would like to make sure that the tone colors nonetheless match up, enter a ¿ in place of the extra character. (so you’d enter a ¿ in the Pinyin field for a character that didn’t have a Pinyin reading, or enter a ¿ in the character field for a Pinyin reading that didn’t have a character).

Editing Entries

Tap on an existing user dictionary entry to view it in the Definition Screen, then tap on the edit button in the top toolbar (or next to the abbreviation icon for the dictionary) to bring up the same Edit Entry screen.

As in New Entry, tap on one of the fields to edit it in a separate screen. Tap on New Entry to leave this entry unchanged and create a new user dictionary entry instead.

Deleting Entries

Tap on “Delete Entry” in the Edit Entry screen to delete the current user dictionary entry.

Bulk Reviewing / Deleting Entries

Go into your user dictionary’s Browse Entries screen to view a sorted list of every entry in the dictionary; tap on “Edit Entries” and tap on each entry that you want to delete to select it, then tap “Delete Entries” to delete them.
