The word "脚尖" (jiǎojiān) is a compound noun formed by combining two meaningful characters: "脚" (jiǎo), meaning "foot," and "尖" (jiān), meaning "tip," "point," or "sharp." It follows a common grammatical structure in Chinese where a general noun ("foot") is modified by a descriptive element ("tip") to create a specific, concrete term—literally "foot-tip," which accurately translates to "tip of the foot" or "toes," referring to the foremost part where the toes are located.
