Welsh people are people who live in Wales. They are the remnant of the Celts who lived in the whole of the British Isles during Roman times and before. Welsh people are proud of their Celtic origin. Welsh people have their own Celtic traditions including distinctive Welsh music. The Welsh male voice choirs are world famous.
It is now known that "Welsh" is actually English as spoken by miners trying to clear coal dust out of their throats. As there is no longer a coal mining industry in Wales it shouldn't be too long before "Welsh" dies out.
