Use Of The A And An Questions Medium
No, you cannot use "an" before a consonant sound. "An" is used before words that begin with a vowel sound, while "a" is used before words that begin with a consonant sound. The choice between "a" and "an" is determined by the sound that follows the article, not necessarily the letter itself. For example, we say "an apple" because "apple" starts with a vowel sound (/æ/), and we say "a university" because "university" starts with a consonant sound (/jʊ/).
