Use Of The A And An Questions Medium
The rule for using "A" or "An" before words starting with a silent "n" is to use "An." This is because the choice between "A" and "An" is determined by the sound that follows the article, not the actual letter. When a word starts with a silent "n," the sound that follows is a vowel sound. Since "An" is used before words that begin with a vowel sound, it is the correct choice in this case. For example, we say "an hour" because the "h" in "hour" is silent, and the word is pronounced with a vowel sound.
