The Celtic nations or Celtic countries are a cultural area and collection of geographical regions in Northwestern Europe where the Celtic languages and cultural traits have survived. The term nation is used in its original sense to mean a people who share a common identity and culture and are identified with a traditional territory.
The six regions widely considered Celtic countries in modern times are Brittany (Breizh), Cornwall (Kernow), Ireland (Éire), the Isle of Man (Mannin, or Ellan Vannin), Scotland (Alba), and Wales (Cymru). In each of these six regions a Celtic language is spoken to some extent: Brittonic or Brythonic languages are spoken in Brittany (Breton), Cornwall (Cornish), and Wales (Welsh), whilst Goidelic or Gaelic languages are spoken in Scotland (Scottish Gaelic), Ireland (Irish), and the Isle of Man (Manx).
