中文词源

molecule 分子

来自拉丁语moles,大块，防洪堤，大工程，大建筑物，-cul,小词后缀。用于化学术语分子。

英文词源

molecule (n.): 1794, "extremely minute particle," from French molécule (1670s), from Modern Latin molecula, diminutive of Latin moles "mass, barrier" (see mole (3)). A vague meaning at first; the vogue for the word (used until late 18c. only in Latin form) can be traced to the philosophy of Descartes. First used of Modern Latin molecula in modern scientific sense by Amedeo Avogadro (1811).
