‘词典’ (cí diǎn) literally means ‘word canon’ — ‘词’ (cí) means ‘word’ or ‘term’, and ‘典’ (diǎn) means ‘classic’, ‘canon’, or ‘authoritative reference work’. Together, they refer to a dictionary focused specifically on words and their meanings, usage, pronunciation, and sometimes etymology — as opposed to a ‘字典’ (zìdiǎn), which is a character dictionary emphasizing individual Chinese characters. Lexicons like 词典 are essential tools for learners and native speakers alike when looking up vocabulary, checking definitions, or verifying collocations.

In practice, 词典 is used broadly for both monolingual (Chinese-to-Chinese) and bilingual (e.g., Chinese-English) dictionaries that organize entries by word rather than by character. It implies authority and comprehensiveness — you’d consult a 词典 for nuanced explanations, example phrases, or grammatical notes, not just basic translations. While modern digital apps often replace physical books, the term remains standard in formal and educational contexts.
