connect: [17] Etymologically, connect means ‘tie together’. It comes from Latin connectere, a compound verb formed from the prefix com- ‘together’ and nectere ‘bind, tie’ (whose past participial stem, nex-, is the ultimate source of English nexus [17]). The derived noun connection first appeared, in the spelling connexion, in the 14th century.
