Noun and its types

The noun means name. In English Grammar, a noun is one of the basic and most important parts of speech.

Definition

A noun can be defined in just one sentence, and that is "Noun is a naming word".

Its only function is to name. If we look around, we see different things in this universe. They may be living things or non-living things, and they are all named by nouns. Therefore, we can say that they are all nouns in the language of grammar.

Are they the only nouns in this universe? 

No.

If the answer is no, what are other nouns?

Types of noun

Generally, there are five kinds of nouns in English Grammar. They are:

1.    Common Noun

2.    Proper Noun

3.    Collective Noun

4.    Concrete Noun

5.    Abstract Noun

We are not going to discuss these kinds of nouns. They are very simple and everyone knows them.

We also define a noun as the name of a person, place, thing, idea, phenomenon, substantive, adjective, numeral, or pronoun.

We are also going to take some examples of all kinds of nouns. Examples are:

School, hospital, apple, Mike, boy, girl, army, team, pain, happiness, ideology.

So, noun names each and everything in the universe, whether it is observable or non-observable. Therefore, nouns can broadly be divided into two categories:

1.    Observable noun

2.    Non-observable noun

Noun also names actions. Gerund and Infinitive are also nouns.

For example:

She is swimming in the pool.

Swimming in the river is dangerous.

Here in the first sentence, the word "swimming" is a verb with an "ing" form, but in the second sentence, the word "swimming" is a noun, which is known as a Gerund.

He wants to buy a car.

To buy a car is very expensive.

Here, both sentences have the phrase "to buy," which is known as an Infinitive, but in the second sentence, it has become a noun. 

Thus, a noun is like a Paris stone that names everything it touches, like a Paris stone turns everything into gold it touches.
