oh i know it was just a guess, but who the fuck sat down and was like, ok y is only gonna be a vowel sometimes? why is it the only letter to get special privilages?
When my time comes, I want to be burried face down. That way, anyone that doesn't like me, can kiss my ass!
Well, I think any letter that takes the place of a vowel could be considered a vowel in that case. I don't think someone sat down and thought this up. Originally, I doubt y was ever used as a vowel. But certain words probably evolved, and in some cases y was takin the place of an i, hence y became a vowel. Again, just a guess.
Y is sometimes a vowel and sometimes a semi-vowel. Vowels have their own syllables, so when used such as in eye and pay, y is not a vowel. It is true, though, that y's use as a semi-vowel is pretty rare these days.
