There are two indefinite articles in English: ‘a’ and ‘an’. They are used before a singular noun that has a plural form. ‘A’ is used before a consonant sound and ‘an’ is used before a vowel sound. The sound is more important than the spelling; we say ‘an hour’ and ‘a bag’ because the sounds of the first letter are different.
