Anyway, I was wondering, in my ill-informed and gormless way, what the " y" in the middle meant ...what was it for ? The thing was, as soon as I found out, I realised I had seen it used in that way already. It doesn't half make you feel a prat.
I had completely forgotten that some Welsh place-names have the definite article before their name ... Y Bala, Y Wyddgrug, Y Wyddfa, Y Trallwng, Y Barri, Y Gelli ..... it's as simple as that.
