I just found out that the name of Arthur’s dog, Cavall/Cafall, translates to “Horse” in middle Welsh.
Is this true? I really hope this is true.
Probably true, today words for horse un Welsh is “Ceffyl” (pronounced with a k sound) somethig that is somehow similar.
Fun thing is it probably shares its origin with today word for horse in romance languages (cavallo, cheval etc) but nobody knows for sure where the word came from its not Latin.
