Here's a breakdown:
* Origins: The proto-Celtic language, the ancestor of all Celtic languages, is thought to have been spoken in mainland Europe around the late Bronze Age and early Iron Age (around 1000 BC).
* Spread: Celtic speakers migrated from mainland Europe westward and northward, reaching areas like the British Isles and parts of modern-day France, Spain, and Portugal.
* Modern Distribution: Today, Celtic languages are spoken in:
* Ireland: Irish Gaelic
* Scotland: Scottish Gaelic
* Wales: Welsh
* Brittany (France): Breton
* Cornwall (England): Cornish (nearly extinct)
* Isle of Man: Manx (extinct)
Therefore, Celtic languages are associated with various countries, reflecting the historical migrations and evolution of these languages.
