From Middle English excusen (verb) and excuse (noun), borrowed from Old French escuser (verb) and excuse (noun), from Latin excūsō, excūsāre (“to excuse, allege in excuse, literally, free from a charge”), from ex (“out”) + causa (“a charge”); see cause, accuse and recuse. Displaced native Old English lād (“an excuse”) and lādian (“to excuse”).
