Y is vowel or not

 Y is considered to be a vowel if…

The word has no other vowel: gym, my.

The letter is at the end of a word or syllable: candy, deny, bicycle, acrylic.

The letter is in the middle of a syllable: system, borborygmus.

 In such cases, the letter y is articulated as either the long vowel e or short or long I (as a rule as a long I when finishing a word)— and, in every practical sense, it is a vowel. At the point when y shapes a diphthong—two vowel sounds participated in one syllable to frame one discourse sound, for example, the "oy" in toy, "ay" in day, and "ey" in monkey—it is likewise viewed as a vowel. 

Commonly, y speaks to a consonant when it gets going a word or syllable, as in yard, legal counselor, or past. In fact, this sound of \y\ is viewed as a semivowel or float, which is a less unmistakable vowel discourse sound that happens in the enunciation of two sequential vowel sounds inconsistent in noticeable quality. For instance, there's a concise long e sound while articulating \y\ in yes. Wind current isn't hindered in sounding \y\ (on the off chance that it was y would be a genuine consonant); in any case, the mouth isn't opened as completely as in articulating the vowel \y\ in right on time. The outcome is a vowel-like consonant.
