I'm a bit of a grammar nerd, but don't know the answer to this question. Yes, I could probably google the answer, but I'm bored!
With a few exceptions "a" is the modifier used with words that begin with consonants, and "an" is used with words that begin with vowels (except in words like unicorn).
So "she is a great mom" and "she is an awesome mom."
When you use an acronym like MOH, do you say, "What's a MOH?" or do you say "What's an MOH?"? M is a consonant, but the sound you make to pronounce "M" starts with vowel sound.
Which is right?
Am I even making sense?
