exactly what the toast means that my uncle uses. He's from South Wales originally, Ebbw Vale to be precise. He doesn't know, because he was in the generation that had the language literally beaten out of them at school. Most of my relatives back there speak little or no Welsh. It sounds to an Aussie like "Yucky Da", or "Yucky Da Bo Beed". I guess it means "good" something, but what? Good luck? Good Health? And how do you spell it correctly? Cheers, Cath
