Middle English -age English -age English average Not entirely certain. The oldest meaning in English is “customs duty”. Borrowed from Middle French avarie (“damage to ship or cargo”), from Old French avarie, from Old Italian avaria where it is first attested in the 12th century in the context of Mediterranean trade. From there most sources trace it to Arabic عَوَارِيَّة (ʕawāriyya, “damaged goods”), from عَوَار (ʕawār, “fault, blemish, defect, flaw”), from عَوِرَ (ʕawira, “to lose an eye”), but the OED gives it a Romance derivation from Italian avere (“property, goods”) or the like. The English suffix -age was added in analogy to words like damage.
