What is Noun?

A Noun is a word used as the name of a person, place or thing. The word 'thing' is used to mean anything that we can think of.
For example:-      This bike is in good working condition.

• When a noun names something you can see or touch, it is called Concrete Noun.

For example:-     wall, house, car, boy, girl, are concrete nouns.

• When a noun names things that can't be seen or touched, it is called an Abstract Noun.

For example:-        goodness, kindness, honesty, wisdom, bravery, etc 
                    There are two types of Nouns:-

1. Common Noun.    A common noun is a name given in common to every person or thing of the same class or kind  ( Common here means shared by all ), as, girl, school, train, etc.
2. Proper Noun.      A proper noun is the name of some particular person or place; as, America, London, France, Shakespeare, are proper nouns. ( Proper means one's own. Hence a proper name is a person's own name )

                    Singular & Plural Nouns:-
The nouns are always in singular and plural forms.

1. Singular Noun.    A noun representing a person, a thing, or a place, is called Singular Noun.

 For example:-    boy. school, college, etc

   2.   Plural Noun.    A noun representing two or more nouns, things or places, is called Plural Noun.
