诗集 (shī jí) is a compound noun meaning 'poetry collection' — a book or volume containing multiple poems, usually by one author or centered on a theme. The first character 诗 (shī) means 'poem' or 'poetry', and the second character 集 (jí) means 'collection', 'anthology', or 'compilation'; together, they literally convey 'a collected set of poems'. This term is used in literary, academic, and publishing contexts, and appears on book covers, library catalogs, and literary reviews.

诗集 is a formal, standard term — not colloquial — and is commonly used when referring to published works (e.g., a famous poet’s complete poems) or curated selections (e.g., contemporary Chinese poetry collections). It implies intentionality and artistic coherence, distinguishing it from casual groupings of poems. While 集 can appear in other compound nouns like 文集 (wén jí, 'prose collection') or 画集 (huà jí, 'art album'), 诗集 specifically denotes poetic works and carries cultural weight in Chinese literary tradition.
