is there any word that doesn't have at least one vowel in ?

Answer 1

It depends - do you mean spoken vowel sounds, or written vowels? And are you referring only to the English language?

In written english, the "vowels" are aeiou. Some short, but recognised and valid, words contain a "semi-vowel" in place of a vowel - words like "fly" or "by".

In spoken english, a (phonetic) vowel sound is made when air passes out of the mouth uninterrupted by the organs of articulation. There are many more phonetic vowels than alphabetic vowels, and the pure vowels sounds ("monophthongs") can also be combined into compound "multiple" vowels (diphthongs and triphthongs).

There are no English words that do not contain spoken vowel sounds. The spoken vowel sounds are vital for word structure in spoken English language.

This is obvious when you transliterate words like "fly" or "rhythm" into a phoneticised form. If you were trying to show someone how to pronounce these words, you might say that they are pronounced "flai" or "ri-them". This clearly shows the presence and placement of the spoken vowels in these "vowel-less" words.
