i was thinking of putting "an" n, but then i read this:
turns out its only before: The rule states that “a” should be used before words that begin with consonants (e.g., b, c ,d) while “an” should be used before words that begin with vowels (e.g., a,e,i).
No lie i really did read this before posting it, but then... i didn't scroll down...
Similarly, you should use “an NBC reporter” (because “NBC” is pronounced “enbisi”) and “a NATO authority” (because “NATO” begins with a “ne” sound).
So yea, i did wright it right, the way it sounded, when i was proofreading, I corrected it and turned out to be wrong...
hopefully my failure gave you a good laugh, productive correction, improper application on your part.
