slave: [13] The word slave commemorates the fate of the Slavic people in the past, reduced by conquest to a state of slavery. For ultimately slave and Slav are one and the same. The earliest record we have of the ethnic name is as Slavic Sloveninu, a word of unknown origin borrowed by Byzantine Greek as Sklábos and passed on to medieval Latin as Sclavus. It was this that was turned into a generic term sclavus ‘slave’, which passed into English via Old French esclave. [slave etymology, slave origin, 英语词源]
