Origin of gospel
- Middle English from Old English gōdspel (ultimately translation of Greek euangelion) gōd good good spel news
From American Heritage Dictionary of the English Language, 5th Edition
- From Middle English gospel, gospell, godspel, godspell, goddspell, from Old English godspel (“gospel, glad tidings; one of the four gospels”), corresponding to god + spell (“talk, tale, story”), believed to be an alteration of earlier *gōdspell (literally “good news”), used to translate ecclesiastical Latin bona annuntiatio, itself a translation of Ecclesiastical Latin evangelium / Ancient Greek εὐαγγέλιον (euangelion, “evangel”, literally “good news”). Compare Old Saxon godspel, godspell (“gospel”), Old High German gotspel (“gospel”), Icelandic guðspjall (“gospel”).
