Origin & History of “parallel”

Etymologically, parallel simply means ‘beside each other’. It comes via French parallèle and Latin parallēlus from Greek parállēlos. this was a compound formed from pará ‘beside’ and allḗlōn ‘each other’, a derivative of állos ‘other’ (to which English else is distantly related).
