Where did Scotland get its name from?

Land of the Scots, from Old English Scottas, "inhabitants of Ireland." Old English borrowed the word from late Latin Scotti, of unknown origin. It may possibly have come from an Irish term of scorn, scuit. After the departure of the Romans from Britain in 423, an Irish tribe invaded Scotland, and the name came with them. It later extended to other Irish who settled in the northern regions of Britain. ,
