Learn how Chinese dictionaries use pinyin, radicals and stroke counts, with a worked character lookup, digital search options and tips for reading entries in context.

Quick Answer: How Do You Look Up a Chinese Character?

A Chinese dictionary offers routes from pronunciation, character shape or typed text to an entry. Choose the route that matches what you already know, then confirm the word’s reading and meaning in context.

If you know the Mandarin sound, search by pinyin (拼音, pīnyīn) using the dictionary’s input rules.
If you recognize the shape but not the sound, use its radical (部首, bùshǒu) and stroke-count index.
If the text is selectable, copy the exact character or whole word into a suitable dictionary.
Read definitions and example words after finding the matching form.

The worked example below uses 休 (xiū), whose meanings include “rest.” Its six total strokes and four strokes outside the radical illustrate two different index fields.

Six stages from choosing a lookup route to checking a word in context.

Finding an unfamiliar character is a search problem; understanding it is a reading problem. A radical index can take you to the right page without telling you which sense fits your sentence. A sound search can offer several candidates, so the sentence still matters.

This guide explains those tasks separately. It sits within the wider Chinese language reference hub, but the pronunciation examples here use Mandarin rather than assuming that one reading covers every Chinese language.

Choose a Route from What You Know

Begin with your strongest clue. The same dictionary may provide more than one route, and a digital interface may combine several filters.^[2][3]

What you know	Useful starting route	Qué verificar
The Mandarin pronunciation	Pinyin or a supported phonetic index	The tone, matching character and intended word
The written shape	Radical and remaining strokes, or a total-stroke index	Which count the index requests
The exact selectable text	Character or whole-word search	That the result preserves the form and word you copied

Read the short instructions supplied with your edition or interface before applying a familiar method. One online learner dictionary, for example, offers radical, total-stroke and phonetic indexes; a specialist variants dictionary also allows structure and combined-condition searches. Neither layout should be assumed to describe every printed dictionary.^[2][3]

Radicals and Remaining Strokes

A radical is an indexing category. It may resemble a visible component of the character, but choosing it is not always obvious. A character’s radical does not by itself provide a full definition or a complete account of its history. See Chinese character radicals for the component-versus-index distinction.

In a radical-and-stroke lookup, first identify the heading, then count the strokes outside the radical. A total-stroke index instead asks for the entire character. Do not enter one count into a field requesting the other.^[1][3]

The familiar 214-radical framework is used in the Unicode radical-stroke system, but it is not a promise about every dictionary. Its documentation also records ambiguous assignments and alternative index values. A failed first attempt can therefore mean that your chosen heading differs from the index’s assignment, rather than that the character is absent.^[5]

Counting should follow the written form and conventions of the resource you are using. The guide to Chinese stroke order can help you recognize stroke units; joined-looking shapes are not counted merely by estimating the number of visible line segments.

A Worked Lookup: 休

For 休, the official learner entry gives four strokes outside the radical and six in total, with the Mandarin reading xiū. Here is how those facts guide a radical lookup.^[6]

Find the radical heading. Look for the person radical 人 (rén), shown as 亻 on the left of 休.
Count the remaining strokes. Exclude the left-hand radical; the rest of this character has four strokes.
Locate the character. Check the four-remaining-stroke group under that radical and compare the printed form with 休.
Read beyond the index. Follow the page reference or entry link and check pronunciation, definitions and example words.

For this example, two radical strokes plus four remaining strokes make six total strokes. The radical heading can show its full form while the character contains a component form. Match the entry’s classification rather than assuming that the heading must look identical to the component in every character.

Pinyin, Readings and Whole Words

If you know the sound, pinyin can be a faster route. Input conventions differ: a resource may accept tone marks, tone numbers or an unmarked syllable, so check its own help rather than assuming one syntax works everywhere.^[1][4]

A single character can have more than one reading. The research-oriented entry for 休 lists xiū, xǔ and xiǔ, while the learner entry presents xiū. The broader entry includes historical uses and explicitly distinguishes its research audience from general learners. More readings in one resource do not mean they are interchangeable in your sentence.^[6][7]

Search whole words as well as characters. For example, 休息 (xiūxí in the cited Taiwan Mandarin dictionary) means “to rest.” The character entry uses it as an example, and the separate word entry explains the expression. Follow the reading supplied by the dictionary for the variety it describes.^[6][8]

A pronunciation search can also return different characters with the same sound. The article on Chinese homophones explains why matching a syllable is only the beginning of identification.

Digital Search and Character Variants

Copyable text is valuable because it preserves the character you encountered. If the dictionary offers separate character and word searches, choose the mode that fits the task. A character result may report radical, remaining strokes, total strokes, pronunciation and variant forms; those are distinct fields.^[1]

Specialist resources can offer searches by components, pronunciation or several conditions together. Use only the filters you can supply confidently. The variants dictionary’s instructions explicitly state that its combined search does not require all available conditions.^[3]

If a result has a different form, check its variant relationship rather than silently replacing the source text. The guide to simplified and traditional Chinese provides background. When using handwriting input or image recognition, compare the proposed character with the original before accepting it; recognition is a way to propose candidates, not proof that one is correct.

Read the Entry in Its Original Context

Once you have a match, return to the full word and sentence. Check which reading belongs to that expression, which definition fits the construction and whether the example is modern, historical or limited to a particular use.

Do not choose a sense simply because it comes first on the page. The broader 休 entry separates readings and grammatical uses and includes historical quotations. Its extra material serves research purposes; it is not a requirement to use every listed sense in modern conversation.^[7]

For an older text, a historical dictionary may be more useful than a short learner definition. The guide to Classical and modern Chinese explains that wider reading distinction. Keep the source sentence beside your notes so that a successful lookup remains connected to the passage you wanted to understand.

FAQs About Chinese Dictionaries

Do all Chinese dictionaries use the same radical list?

No. Check the index used by your particular resource. The 214-radical framework is one established system, and radical assignments or alternate lookup values can require attention even within documented indexing systems.^[5]

Should I count total strokes or strokes outside the radical?

Use the count requested by the index. A radical-and-stroke lookup commonly uses strokes outside the radical; a total-stroke index uses the whole character. For 休, those figures are four and six respectively.^[3][6]

Can I translate a word by adding its character meanings?

Individual character entries can help, but confirm the whole expression in a word entry and its sentence context. Finding the right characters does not automatically identify the intended meaning of a compound.
