* Insular Celtic: Spoken on the islands of Britain and Ireland. This branch includes:
* Goidelic languages: Irish, Scottish Gaelic, Manx
* Brythonic languages: Welsh, Cornish, Breton
* Continental Celtic: Spoken in mainland Europe. This branch is now extinct, but included languages like:
* Gaulish: Spoken in Gaul (modern France)
* Celtiberian: Spoken in the Iberian Peninsula
* Lepontic: Spoken in the Alps
* Galatian: Spoken in Anatolia (modern Turkey)
It's important to note that the classification and relationships between these languages are still a topic of debate among linguists.
While we know that the Celts spoke these languages, we don't know exactly how they sounded. There are some surviving inscriptions and texts, but these are limited and don't provide a complete picture.
The Celtic languages have a rich history and continue to be spoken by millions of people today, primarily in Ireland, Scotland, Wales, and Brittany.
