中文詞源
molecule 分子
來自拉丁語moles,大塊，防洪堤，大工程，大建筑物，-cul,小詞后綴。用于化學(xué)術(shù)語分子。
英文詞源
- 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).
