Anglo-Saxons
The native British people, who wrote in both Latin and Welsh (a Celtic language), referred to these invaders as Saxones or Saeson. The latter name is still used today in the Welsh word for English people, Saeson, the English language, Saesneg, and things related to England, Seisnig. In the Scottish Gaelic language the word for an English person is sasannach and in Irish the word is sasanach.
