 In the first millennium BC came the Iberians from the south.Although their identity is still a matter of debate, some theories posit that they spoke an Afro-Asiatic language, and that they separated from the Berbers in North Africa and moved into Spain and then further north to the south of modern-day France.In Cerdanya they probably mixed with the native inhabitants, and the resulting people were known as the Kerretes, from the native word "ker" or "kar", meaning "rock", related to old Basque "karri" (modern Basque "harri"), "stone".
