what language did King Arthur really speak (historically) please provide proofs to back it up?

Answer 1

King Arthur would not have spoken "Welsh". He would have spoken Brythonic, the ancestor language of Welsh, Breton, and Cornish. The specific dialect of Brythonic spoken in non-Welsh Britain died out after the Anglo-Saxon invasion, so there is no surviving language that reflects the dialect of Brythonic that King Arthur spoke. However, according to the movie "King Arthur", he would have spoken Latin since he was of Roman descent in that film.

Answer 2

No proof available as there is no proof that King Arthur was a real person. The first mention of him comes in about 1200, but the period he was supposed to exist in was at the time when the Anglo-Saxons were conquering England. There were many wars between about 450 and 600 AD, but we only have accounts written a long time afterwards, which may not be accurate.

Anyway, Arthur would have been a leader of the Britons fighting the Anglo-Saxon invaders. The Anglo-Saxons spoke a very early form of English - "Angle-ish"; the Britons spoke an early form of Welsh. That was the language spoken over most of Britain throughaout the Roman period.

Answer 3

King Arthur would have spoken Welsh. The Anglo Saxons hadn't invaded Britain in his time. His father was called Uther Pendragon, the surname meaning "Dragon's Head". His wife was called Gwyn Hwyfar ("white shadow"). He had knights with names like Geraint and Gareth. What could be more Welsh?

Answer 4

In addition to English, he spoke Spanish (taught in the English schools, and since he had already taken Latin, he figured it was an easy A). What's more surprising though is that he could sign, using American Sign Language - though the New World had not yet been discovered, he knew that if a gorilla could learn it, he could too, and so he did.
