Hi,
Which is correct a history or an history? An UFO or a UFO. I've always believe that since the letter h is pronounced in history it should be a history. Yes
Words like a master of business administration or an MBE since M is pronouced as "em". Yes
Any word beginning with a vowel or pronounced like a vowel is preceded by an. ex: an eagle, an angel, an UFO,
a UFO, it's like a young man
"an honor" the h left out when pronouced hence an.
