Pronunciation

  • /ɪntə(ɹ)ˈtʃeɪndʒ/, /ɪntɚˈt͡ʃeɪnd͡ʒ/[1]

Etymology

It is inherited from Middle English enterchaungen,[2][3][4] borrowed from Old French entrechangier (“to exchange”),[5][3][6][2] formed from entre- (“between”), from Latin inter-, and changier (“to change”).[5][3][6] The Anglo-Norman verb is recorded from the mid-12th century, meaning to exchange and to alternate.[7] The English spelling was later altered to inter- after Latin.[8][9][10] The noun, first enterchaunge, is partly borrowed from Old French entrechange and partly formed from the verb;[3][11][5] the Anglo-Norman noun dates from about 1170.[7] Both go back to change.[3][12]

Earliest recorded meaning

To exchange things with each other; to give and receive in turn: about 1374, in Chaucer's Troilus and Criseyde, where the lovers exchange rings.[5][2][4]

Semantic evolution

Chaucer also used the verb, in his Boethius, for putting each of two things in the place of the other.[5] From 1483 it could mean to alternate; from 1561 it also meant to make things follow by turns.[5] Etymonline dates the noun to the early 15th century,[3] while the OED and Barnhart give 1548 for the act of reciprocal exchange;[5][4] the sense of alternation followed in the 1550s,[5][3] and Johnson (1755) quoted Milton's "sweet interchange of hill and valley".[13] The railway sense of passing between lines appears in 1887, and the road junction where traffic streams don't cross in 1944, first in the Baltimore Sun.[5][3]
