From Middle English companion, from Old French compaignon (“companion”) (modern French compagnon), from Late Latin compāniōn- (nominative singular compāniō, whence French copain), from com- + pānis (literally, with + bread), a word first attested in the Frankish Lex Salica as a translation of a Germanic word, probably Frankish *galaibo, *gahlaibo (“messmate”, literally “with-bread”), from *hlaib (“loaf, bread”). Compare also Old High German galeipo (“messmate”), Gothic 𐌲𐌰𐌷𐌻𐌰𐌹𐌱𐌰 (gahlaiba, “messmate”), Old Armenian ընկեր (ənker, “friend”, literally “messmate”). More at co-, loaf.
