Firstly, you spelt vowel wrong with a y replaced with a w.
Secondly, Y is not considered a vowel. Although, some words are pronounced with the y sounds like i like fly but normally it sounds like a consonant more like a vowel. Some people think y is a vowel because when y forms a diphthong, two vowel sounds joined in one syllable to form one speech sound, but most of the words like yard, lawyer, beyond don’t pronounce with the y that sounds like i. So with that being said, y is more preferred as a consonant more than a vowel.
