effect
English
Etymology
For noun: from Middle English effect, from Old French effect (modern French effet), from Latin effectus (“an effect, tendency, purpose”), from efficiō (“accomplish, complete, effect”); see effect as a verb. Displaced Old English fremming, fremednes from fremman.
For verb: from Middle English effecten, partly from Medieval Latin effectuō, from Latin effectus, perfect passive participle of efficiō (“accomplish, complete, do, effect”), from ex (“out”) + faciō (“do, make”) (see fact and compare affect, infect) and partly from the noun effect.
