“corresponding (to some other) in particulars,” 1640s,源自拉丁語 analogus,來自希臘語 analogos,“成比例的,按照適當的比例”,由 ana “貫穿; 根據”(見 ana-)和 logos “比率,比例”組成,是一個專業用語(見 Logos)。通常與 to 或 with 一起使用。
A term is analogous whose single signification applies with equal propriety to more than one object: as, the leg of the table, the leg of the animal. [William Flemming, "The Vocabulary of Philosophy," 1858]
