When should I use “a” versus “an” in front of a word beginning with the letter h?
What's the proper wording here, neither one sounds right to me:
"Chevra, an humanitarian organization..."
or
"Chevra, a humanitarian organization..."
My instinct says it follows the same rule as "an hour", but the 'h' sound is more pronounced in 'humanitarian', so I'm unsure.
