Do you use “a” or “an” before acronyms?
What article should be used directly in front of an acronym that begins with 'N?' Since the pronunciation of the letter 'N' begins with a vowel sound, would 'an' be correct?
I asked the same question and it was closed. The consensus here seems to be "do whatever you want"; I use the article corresponding to saying the English-language, expanded version, so that people who read it most properly won't complain.
