From Middle English replyen, replien, borrowed from Old French replier (“to reply”), from the Latin replicō, replicāre (“I fold back”) (in Late or Medieval Latin "to reply, repeat"), from re + plicō (“to fold”); the noun derives from the verb by nominalisation. Doublet of replicate and replica.
Commonly takes the preposition 'to' before the person or message being answered.
