Grammar question: When to use "a" instead of "an"?
So we all know that in modern English usage, we say an alligator, an eagle, an umbrella, etc. before a word that starts with a vowel. My specific question then, is why do we say a unicorn, even though unicorn starts with a vowel? Why don’t we say an unicorn?
