NOUNS: NUMBER

Number: In nouns, number means the method representing whether we are talking of one thing or of more than one. Language has two numbers – Singular and Plural. The singular number shows that one thing is meant; the plural, more than one.

There are only two numbers in English:

1. Singular Number : A noun is singular in number, when it indicates only one person, object or thing.
Example: a man, a girl, a boy, a kite, a chair, and so on.

2. Plural Number : A noun is plural in number, when it points to more than one person or thing.
Example: four mangoes, two horses, ten books, and so on.
