No no!

You're all wrong and I'm right!

"Wale" as in the Saxon word for foreigner (As in those smelly Celtic chaps we've displaced in order to found En-gur-land, so we can be frustratingly crap at football a millenium and a half from now).

Hence Wales...and the objection of many Cwmraig to that word.

"dich" as in ditch or dyke, or other earthen barrier that an unsuspecting Saxon might happen to fall in while exploring a new area of his/her new homeland.
