Etymology: "Unchanger" is formed from the English prefix "un-", meaning "not," attached to "changer," which comes from Old French "changeor," a derivative of "changer," meaning "to change" (ultimately from Latin "cambiare," "to exchange"). The "-er" ending turns the verb into an agent noun, a person or thing that does the action, so "changer" is one who changes, and adding "un-" reverses it into one who does not change. The word is a transparent compound rather than a term with a documented first appearance or a famous coiner. Its meaning follows directly from its parts: a stubborn traditionalist, or anything that stays fixed while everything around it shifts. It is uncommon in general usage and appears mainly in older or literary English, where writers sometimes build such nouns from "un-" plus an agent noun to name a type of person or thing.
