Cambria

Cambria is the classical name for Wales, being the Latinised form of the Welsh name Cymru (Wales). The etymology of Cymry "the Welsh", Cimbri, and Cwmry "Cumbria", improbably connected to the Biblical Gomer and the "Cimmerians" by 17th-century celticists, is now known to come from Old Welsh combrog "compatriot; Welshman", from the root *brogi "country"; "territory" (cf. Welsh, Cornish, Breton bro "territory"; "country"), itself from *mrogi (cf. Old Irish mruig, gen. mroga "country"), deriving from an old Brythonic word *com-brogi or Proto-Brythonic *kom-brogos, meaning "fellow countryman"; "compatriots", (as a result of the struggle with the Anglo-Saxons) possibly therefore related to its sister language Breton's keñvroad, keñvroiz, "comrade", "compatriot".
