Etymology
the word 'ineffaceable' is built upon the french verb 'effacer', which literally meant 'to remove the face or surface' of something, derived from the latin elements 'ex-' (out) and 'facies' (form, appearance, face). the negative prefix 'in-' (not) was added to create the opposite meaning, and the productive suffix '-able' (capable of being) was appended to form an adjective. thus, the literal construction "not capable of being erased from the surface" evolved into its modern abstract sense of something so permanent or deeply impressed that it cannot be removed or forgotten.
Analysis
in- (latin origin, a prefix meaning 'not'); efface (from french 'effacer', meaning 'to erase', itself from latin 'ex-' (out) + 'facies' (face, appearance)); -able (latin suffix '-abilis', forming adjectives meaning 'capable of, fit for').
