No, it isn't.
no
actually I seem to recall a geological term of Scandinavian derivation GWM refering to a glacial lake.
You may be thinking of an acronym. GWM can stand for Ground Water Management or Monitoring. You may be right, but a hasty search doesn't support it.
But the word cwm (pronounced coom to rhyme with loom) has been imported from Welsh to mean a hollow at the head of a mountain valley. In this case the w is a vowel.
How about the word "vowel" itself? Or the word "vow"?
'W' cannot be a vowel, the only interchangeable letter is 'y'. Here in the word 'two' 'w' is a silent consonant.
The Welsh word crwth, borrowed directly without Anglicised spelling, sometimes appears in English dictionaries. In proper English, w is a vowel only when combined with another vowel, as a diphthong such as how or in words like yawn.
The middle letter of the word "vowel" is "w."
No. Contrary to what some people say, "W" is never a vowel in the English language.
not a vowel
'Wife' has a long vowel sound: w-eye-f.
Three: v, w, and l.
Yes. The A is a long A sound, as in sale and pale. The E is silent.
The vowel O in owl is controlled by the following W, making the vowel neither short or long. It makes the sound OW, as in COW.
The vowel sound for "one" is a short U, with a W preceding. (wun)
The O in "once" has a W-short U (wuh) vowel sound, as does the number one (wun).
