Sir Kay

In Arthurian legend, Sir Kay /ˈkeɪ/ (Welsh: Cai, Middle Welsh Kei or Cei; Latin: Caius; French: Keu; French Romance: Queux; Old French: Kès or Kex) is King Arthur's foster brother and later seneschal, as well as one of the first Knights of the Round Table. In later literature he is known for his acid tongue and bullying, boorish behaviour, but in earlier accounts he was one of Arthur's premier warriors. Along with Bedivere, with whom he is frequently associated, Kay is one of the earliest characters associated with Arthur. Kay's father is called Ector in later literature, but the Welsh accounts name him as Cynyr Ceinfardqfog.
