What did Celts speak?

The Celts were a group of people who lived in Europe from the Iron Age onwards. They did not speak a single language, but rather a family of related languages called Celtic languages.

Here are some of the main branches of Celtic languages:

* Insular Celtic: This branch includes languages spoken on the islands of Britain and Ireland, such as:

* Gaelic: Spoken in Ireland, Scotland, and the Isle of Man.

* Brythonic: Spoken in Wales, Cornwall, and Brittany (France).

* Continental Celtic: This branch includes languages spoken on the mainland of Europe, such as:

* Gaulish: Spoken in Gaul (modern-day France).

* Celtiberian: Spoken in the Iberian Peninsula.

* Lepontic: Spoken in the Alps.

It is important to note that many of these languages are extinct, and only a few, such as Irish, Scottish Gaelic, Welsh, and Breton, are still spoken today.

It's also worth mentioning that the exact relationship between the various Celtic languages is still debated by linguists. However, it's clear that they shared a common ancestor, and many of them have similar vocabulary and grammatical features.
