peacemaker
n. US //ˈpisˌmeɪkɝ// UK //pˈiːsmeɪkɐ// peace·mak·er
Compound of peace + maker. First attested in the Tyndale Bible from 1526, as a translation of Koine Greek εἰρηνοποιοί (eirēnopoioí, “peacemaker”), a hapax legomenon found in the New Testament. (The Wycliffe Bible from 1395 instead uses "pesible men", to translate Latin pacifici from the Vulgate)
