The "cwm" entry mentions the other use of w as vowel in English, "crwth," and defines it as "crowd." While this is perfectly correct, it may or may not be useful to note that this "crowd" is not what you think, but a 14th century stringed instument.

Welcome PK - so an orchestra of crwth players would be a crowd of crowders?

Zed,
Very pleased to find that note was useful to someone!

So, PK, cwm brought you out of lurkhood, eh? I am glad to see your posts! :-)
