remain: [14] Latin manēre meant ‘stay’ (it has given English manor, mansion, permanent [15], etc). Combination with the prefix re- ‘back, in place’ produced remanēre ‘stay behind, remain’, which passed into English via Old French remanoir. Its present participle gave English remnant [14]. A variant of remanoir was remaindre, which is the source of English remainder [15].
