I think William should have learned Welsh?

[antelopevalley]

William is the new Prince of Wales. He has known for years he will be, but still only knows a few Welsh words.
Charles learned to speak Welsh and can have conversations with people and has given many speeches in Welsh.
I don't understand why William has not done the preparation his father did for this role?

And you know every single one of these fluent speakers?

Well to be fair @KirstenBlest , Wales is mostly populated with sheep…

There are things called surveys of the population
