羊群 is a compound noun meaning 'flock of sheep'. It combines two characters: 羊 (yáng), meaning 'sheep' or 'goat', and 群 (qún), meaning 'group', 'herd', or 'flock' — a classifier-like noun used for collective animals. Together, they denote a natural grouping of sheep, typically under human care or in the wild. Unlike English, where 'flock' can apply to birds or other animals, 羊群 is specific to sheep and rarely used metaphorically.

This term appears in agricultural, pastoral, and descriptive contexts — such as describing grazing in grasslands, livestock management, or rural scenery. It’s neutral in register, commonly found in textbooks, news reports about animal husbandry, and children’s stories. Note that 羊群 is not pluralized in Chinese; context or numerals (e.g., 一群羊) indicate quantity. It does not imply ownership unless specified by context or modifiers like 牧民的羊群 ('the herder’s flock').
