Cornwalln.

CornwallOld English Cornwalas (891), Cornubia (c.705), "the Corn Welsh," from original Celtic tribal name, *Cornowii, Latinized as Cornovii, literally "peninsula people, the people of the horn," from Celtic kernou "horn," hence "headland," from PIE *ker- (1) "horn; head, uppermost part of the body" (see horn (n.)), in reference to the long "horn" of land on which they live. To this the Anglo-Saxons added the plural of Old English walh "stranger, foreigner," especially if Celtic (see Welsh).
