Which is correct a angus or an angus?

Answer 1

"An Angus" is correct because Angus has a vowel in front. Thus it is proper grammar to insert "an" in front, not "a." If there was a consonant in front, like the "b" in Brangus or the "s" in Simangus, then we would only need to have "a" in front in a sentence.

Answer 2

"An angus" is correct because we use "an" before words that begin with a vowel sound, and in this case, the "a" in "angus" is pronounced like a vowel.
