Word Origin:
late 15th cent.: from French avarie ‘damage to ship or cargo’, earlier ‘customs duty’, from Italian avaria, from Arabic ‘awār ‘damage to goods’; the suffix -age is on the pattern of damage. Originally this referred to a tax on exported goods. The meaning later changed so that it referred to money due from goods that had been lost or damaged at sea. It referred specifically to the way the losses were divided between the owners of the vessel and the owners of the cargo (late 16th cent.). This gave rise to the general sense of calculating the mean (mid 18th cent.).
