There are two types of dictionaries regularly used in the Chinese language: 'character dictionaries' list individual Chinese characters, and 'word dictionaries' list words and phrases. Because tens of thousands of characters have been used in written Chinese, Chinese lexicographers have developed a number of methods to order and sort characters to facilitate more convenient reference.

A dictionary is a listing of lexemes from the lexicon of one or more specific languages, often arranged alphabetically, which may include information on definitions, usage, etymologies, pronunciations, translation, etc. It is a lexicographical reference that shows inter-relationships among the data.
