Does an Come Before Vowels?

The rule is: Use an before a word beginning with a vowel sound (not letter). It doesn't matter how the word is spelled. ... Use a before a word with a consonant sound as well as y and w sounds.

Should it be A or an?

Use “a” before words that start with a consonant sound and “an” before words that start with a vowel sound. ... Just remember it is the sound that governs whether you use “a” or “an,” not the actual first letter of the word. One complication is when words are pronounced differently in British English and American English.

Where do you put an?

Using "An" and "A"

The sound of a word's first letter determines whether to use "an" or "a." If the word starts with a vowel sound, you should use "an." If it starts with a consonant sound, you should use "a." For example: Buy a house in an hour.
