Question

which English word has no vowel​

Answer 1

Twyndyllyngs is the longest word in English that doesn't contain one of the five vowels

Answer 2

Answer:

Cwm and crwth do not contain the letters a, e, i, o, u, or y, the usual vowels (that is, the usual symbols that stand for vowel sounds) in English. But in those words the letter w simply serves instead, standing for the same sound that oo stands for in the words boom and booth.
