Wealas
Wealas is a historical exonym used in medieval English and Latin sources to refer to the Welsh people and, more broadly, to Celtic-speaking inhabitants of Britain. The term ultimately derives from Old English Wealas, a word that denoted foreigners and non-Germanic peoples, and it is part of a broader family of Germanic ethnonyms for Celts and other non-Germanic groups. In this context, Wealas came to designate the Welsh and, at times, Britons more generally in early medieval writings.
Etymology and linguistic notes point to a connection with Proto-Germanic roots around the concept of “foreigners.”
Usage and attestations: Wealas appears in various early medieval English chronicles, poetry, and Latin annals as
