Do you mean What is Wales?

Wales is part of Great Britain and the United Kingdom, but the Welsh are Welsh, not English

Never refer to the Welsh as English…
When you interact with Welsh locals, refrain from saying ‘England’ when you mean Britain or the UK, and don’t using it as a blanket term to refer to all inhabitants of the British Isles either.

For instance, it’s like calling an Australian a Kiwi or referring to a Texan as a Yankee and it could ruffle a few feathers over a pint.

The Welsh are able to speak both Welsh and English, roughly one-fifth of the population speaks Welsh.

The Welsh language is one of the oldest Celtic in Europe and recognised as the country’s official language by the Wales National Assembly.
