The Welsh-English Dictionary gives cwm 1. valley n.m. http://www.geiriadur.net/ My Geography teacher taught us many years ago that it especially referred to a valley created by glaciation scooping out a mountain side. It is related to the English place names ending in coombe or combe, such as Ilfracombe.
