noun
Rare and somewhat archaic term for a word list or dictionary; in modern Japanese, 辞書 or 辞典 are overwhelmingly more common.
古い文献では「辞彙」という言葉が使われていることがある。
In old documents, the word 辞彙 is sometimes used.
Rare kanji form; the word is usually written in kana or replaced by 辞書 or 辞典 in modern Japanese.
Kana spelling; more common than the kanji form, but the word itself is rare.
The kanji 辞 means 'word' or 'expression', and 彙 means 'collection' or 'compilation'. The exact historical derivation is uncertain, but the word likely originated as a scholarly term for a glossary or lexicon.
