1. Q-Celtic languages:
- Scottish Gaelic (Gàidhlig): Spoken in parts of Scotland, primarily the Highlands and Western Isles.
- Irish Gaelic (Gaeilge): Spoken in Ireland and is the official language of the Republic of Ireland.
- Manx Gaelic (Gaelg): Spoken on the Isle of Man.
2. P-Celtic languages:
- Welsh (Cymraeg): Spoken in Wales.
- Cornish (Kernewek): Spoken in Cornwall, England.
- Breton (Brezhoneg): Spoken in Brittany, France.
The term "Gaelic" is often used to refer to Scottish Gaelic, Irish Gaelic, and Manx Gaelic collectively, as these languages share many similarities and have common roots. However, when speaking about the broader group of Celtic languages, it is more accurate to refer to them individually or use the term "Celtic languages" to encompass all of them.
