The Chinese word 马铃薯 for "potato" is formed by combining three characters: 马 (horse), 铃 (bell), and 薯 (tuber). This term likely originates from the potato plant's characteristics, where 铃 refers to the bell-shaped flowers of the plant, 马 may imply a large size or foreign origin (as potatoes were introduced to China), and 薯 denotes its classification as a tuberous root vegetable, together creating a descriptive compound for the potato.
