A Model T Ford and a Volkswagen are both cars, have four wheels, and run on gasoline so comparing them would be an example of an analogy.
“energize” is formed from “energy” by analogy with “apologize” from “apology”; Old English “handa” became “hands” on analogy with other plurals in -s.
Origin of analogy
- Middle English analogie from Old French from Latin analogia from Greek analogiā from analogos proportionate analogous
From American Heritage Dictionary of the English Language, 5th Edition
- From Latin analogia, from Ancient Greek ἀναλογία (analogia), from ἀνά (ana) + λόγος (logos, “speech, reckoning”)
