- Scot
- Old English Scottas (plural) "inhabitants of Ireland, Irishmen," from Late Latin Scotti (c.400), of uncertain origin, perhaps from Celtic (but answering to no known tribal name; Irish Scots appears to be a Latin borrowing). The name followed the Irish tribe which invaded Scotland after the Romans withdrew from Britain in 423 C.E., and after the time of Alfred the Great the Old English word described Irish who had settled in the northwest of Britain.
