salvage: [17] The salvage of a ship is etymologically simply a payment made for ‘saving’ it. The word comes via Old French salvage from medieval Latin salvāgium, a derivative of late Latin salvāre ‘save’ (source of English save). The use of English salvage as a verb is a comparatively recent development, dating from the 1880s. => save[salvage etymology, salvage origin, 英语词源]
