The Chinese word 词汇 (cíhuì), meaning "vocabulary" or "lexicon", is a compound formed by combining two morphemes: 词 (cí), which means "word" or "term", and 汇 (huì), which means "to gather" or "to collect". Together, they create a semantic compound where the second character modifies the first, resulting in the concept of "a collected body of words" or "a lexicon". This structure is typical in Mandarin, where two related characters are joined to form a new, more specific abstract noun.
