The Chinese word 松树 (sōngshù), meaning "pine tree," is a compound noun formed through semantic combination, where the first character 松 specifically denotes "pine" (referring to the type of tree) and the second character 树 means "tree" (the general category). This structure follows a common Chinese word-formation pattern where a specific modifier (松) is placed before a more general, categorical head (树) to create a precise, yet transparent and logical, term for a specific kind of entity within that category.
