However, today I had a nice surprise to find that a fellow member of a local club is a Welsh speaker, and used to be president of the Welsh Society at the university where he taught. He used to be a high-powered academic, but is now retired, not that academics of his seniority ever fully retired. Despite being high powered he is very nice and friendly, and kindly took my details and promised to keep me informed of Welsh-oriented social events, like a Welsh-speaking party that he organises at his house.
We exchanged a few words of Welsh. Needless to say, I had a certain amount of brain freeze, but I was able to come out with one or two complete sentences that SSiW learners would have recognised. Being an adademic, it's possible he speaks "posh Welsh" himself, but he was too well-mannered to look down on my version.

He said he was "Liverpool Welsh". Does that imply that what he spoke would be North Walian?
