evangel

From Middle English evaungel, evangile, from Old French evangile, from Late Latin evangelium, from Ancient Greek εὐαγγέλιον (euangélion, “good news”), from εὐάγγελος (euángelos, “bringing good news”), from εὐ- (eu-, “well”) + ἀγγέλλειν (angéllein, “to announce”) (English angel). The word gospel is from the same Ancient Greek origin, also meaning “good news”, but translated into Latin, then calqued into Old English.
