And W is still a vowel in them.

Yes. That's why it dawned on me earlier in this thread. Was GF asing about words with no graphemic or phonemic vowels. That's why I mentioned clicks (link), nasals, and (af)fricatives. I'd consider tsk /|/, hmm /m:/, and sss /s:/ to be interjections (a kind of word). None of them has either kind of vowel in them.


Ceci n'est pas un seing.
