"An" and "A" are articles in english language.

1. "An" is used to denote any singular noun that starts with any of the vowels (a,e,i,o,u).

eg: An apple, An engine, An ice-cream, An umbrella, An orange

2. "A" is used to denote any singular noun that starts with any of the consonants.

eg: A horse, A girl, A man, A book.

Note: We do not use "a" or "an" when we refer to plural nouns.

Here are three ways to turn any noun into a plural.

1. Adding "s" is the most common one. eg: bag - bags

2. For nouns ending with s, ss, sh, sh, x or o we can add "es" to make it a plural. eg: brush-brushes, dress - dresses, box-boxes, bus-buses, Foe-Foes

3. For nouns that end with f or fe we remove the f or fe and add "ves" to

make it plural. eg: scarf-scarves, wife-wives

4. For nouns ending with y we can remove y and add "ies" to make it plural

eg: baby-babies

Some exceptions are Key-Keys, Boy-Boys
