The Chinese word 凳子 (dèngzi), meaning "stool" or "bench", is a compound noun formed through a common morphological process. Its core is the morpheme 凳 (dèng), which historically and semantically represents the stool itself. The character 子 (zi) is added as a noun suffix, a highly productive feature in Mandarin that often nominalizes words, indicates a small or familiar object, or simply creates a disyllabic word for rhythmic and colloquial ease. Thus, the combination fuses a specific semantic root with a grammatical particle to create a complete, everyday vocabulary item.
