From Middle English remainen, from Old French remain-, stressed stem of remanoir, from Latin remaneō, maneō, from Proto-Indo-European *men- (“to stay”). Displaced native Middle English beliven, bliven (“to remain”) (from Old English belīfan (“to remain, stay”)) due to confluence with related Middle English beleven (“to leave behind”), with which it merged. More at beleave and belive.
