## Etymology
From Middle English perfit, from Old French parfit (modern: parfait), from Latin perfectus, perfect passive participle of perficere (“to finish”), from per- (“through, thorough”) + facere (“to do, to make”). The spelling was modified in the 15th century to conform to its Latin etymon. Doublet of parfait, perfecto, and perfectus.
Displaced native Old English fulfremed.
