Let's be perfectly clear on this: neither "A" nor "Y" or "Z" is a vowel, nor a consonant. All three of them are glyphs, symbols, shapes on a screen (or, once upon a time, paper); they're letters. Vowels, like consonants, are sounds: "beat" has one, "sequoia" has three, "cry" has one.
OK, that's obviously disingenuous, because as you were probably already planning to post angrily, letters stand for sounds. Not as reliably in English as in many other written languages, but they stand for sounds nonetheless. And to that end, we generally refer to letters as "vowels" and "consonants" based on the sounds they stand for. A, E, I, O, and U almost always represent vowel sounds, so we call them vowels; B, C, D, and so forth through X and Z, almost always represent consonant sounds, so we call them consonants; and Y sometimes represents a vowel sound ("my", "cry"), and sometimes represents a consonant ("you", "papaya"). There's really no way around it. |
