One word is "cwm", and another is "crwth".
Cwm is a basin at the bottom of a mountain.
Crwth is an ancient Celtic musical instrument.
W as a vowel in WelshThe Welsh language uses "w" as a vowel with a sound somewhere between the "oo" in "book" and the "u" in "buck", so other words borrowed from Welsh may have obsolete spellings with "w" as a vowel.
***By the way, the aforementioned word "crwth" can also be spelled "cruth" or "crowd".
Other examples with "w" as a vowel appear in place-names. "Bwlch" means a pass or gap. "Pwll" means a pool or puddle or pit. The other two words are used in English and appear in dictionaries. These two primarily appear in specialized dictionaries, such as some geographical dictionaries. However, "bwlch" appears in the Oxford Rhyming Dictionary and, apparently, the game Balderdash.
As a clear example of using "w" as a vowel in Welsh, the Welsh language spells "Russia" and "Sudan" as "Rwsia" and "Swdan".
"There are 2 consonants in sew, as 's' and 'w' are consonants and 'e' is a vowel. 'A' 'E' 'I' 'O' and 'U' are vowels, and every other letter in the English language is a consonant." Actually, the word "sew" has only one consonant: s. When the letter "w" ends a word after following a vowel (or in other places where it forms a "diphthong"), the "w" is technically a vowel.
In the English language the only letter that can be considered a consonant or a vowel is the letter Y. The letter W is a consonant.
W is a vowel sometimes, as is Y. There are words in Welsh that use only a W. An example would be the word tow. Without the W the O would not be long. This illustrates that the W is forming a diphthong, which mirrors the use of the letter U from which it developed. After a vowel, W is considered as a vowel, with an "au, oo, or oh" sound. Before a vowel it is considered a consonant, with its "wh" sound.
All words have to have a vowel in them. The five orthodox ones are a,e,i,o,u. However in words such as 'why' and 'sky', the 'y' can be taken to be the vowel. Y is considered a semi-vowel.
Many words have W for a vowel, such as awe, bow, cow, dew, ewe, few gew-gaw, hew, jaw, known, lawn, maw, now, owe, pew, raw, sew, tow, vow, wow and yawn. However, in these cases, the W is only technically a vowel, because it contributes a vowel sound, as would the letter U, from which it originates. Some words, especially Welsh, use the W as the primary vowel, much as Y is used in English. One example is the word "cwm" (valley). (see related question)
'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.
How about the word "vowel" itself? Or the word "vow"?
No a W is never a vowel. The only vowels are A,E,I,O,U and sometimes Y no, there are only five vowels in the English alphabet: A, E, I, O, U; once in a while though we use Y as a vowel as in the word FLY
No. Contrary to what some people say, "W" is never a vowel in the English language.

The "i" is the only vowel in "which", and it has a short vowel sound.
Three: v, w, and l.
'Wife' has a long vowel sound: w-eye-f.
In the English language the only letter that can be considered a consonant or a vowel is the letter Y. The letter W is a consonant.
There are only one vowel, which is "u," in the word "fun."
