dictionary of Chinese characters
A reference work that lists and explains Chinese characters, similar to a character dictionary or lexicon. The term is somewhat technical and may be encountered in academic or historical contexts.

字典 is a more common term for a character dictionary, while 字彙 is a less frequent, somewhat formal or specialized synonym.
漢和辞典 is a Japanese dictionary of Chinese characters with Japanese readings and explanations, whereas 字彙 can refer to a character dictionary in general, not necessarily with Japanese annotations.
The term is composed of 字 (character) and 彙 (collection, compilation). The exact historical derivation is uncertain, but it follows a common pattern for naming reference works.
