replaceable

The word "replaceable" is a modern English formation built upon the verb "replace," which itself entered English in the late 16th century from Middle French replacer, meaning "to put back in place." The French term combined the Latin prefix re- ("again") with the verb placer ("to place"). The suffix -able, of Latin origin via French, was then appended to create the adjective, shifting the meaning from the action of putting something back to the inherent quality of being capable of that action. Thus, the literal morphemic logic of "capable of being put back (or again)" evolved into the modern abstract senses of being substitutable or not indispensable.

Structure: re (again) + place (to put) + able (capable of) - re: Latin origin, a prefix meaning "again" or "back". - place: From Old French placer, ultimately from Latin platea ("broad street, courtyard"), functioning as the core verb meaning "to put or set". - able: From Old French -able, from Latin -abilis, an adjective-forming suffix meaning "capable of, fit for, tending to".
