Technically, no words can be formed without vowels. This is because vowels are the core of syllables, which are the building blocks of words. Every syllable must have a vowel sound.
However, there are some words that appear to be without vowels, like:
* "Rhythm" - The "y" acts as a vowel sound in this word.
* "Fly" - The "y" is pronounced like a vowel.
* "My" - Again, the "y" acts as a vowel.
* "Shrdlu" - This is a made-up word, but it demonstrates the concept. It's pronounced like "shroud-loo," with the "u" being the vowel sound.
So, even words that look like they lack vowels actually have a vowel sound present in their pronunciation.
