Noun

In most languages, including English, nouns are the most common type of word. A noun is a term that describes something (a table), a person (Mahatma Gandhi), an animal (a cat), a location (Delhi), a trait (hardness), an idea (justice), or an activity (yodeling). It's usually a single word, but it's not always: nouns include cake, shoes, school bus, and time and a half.

Common Noun

A common noun is a word that refers to a person, place, or thing without being the name of that person, place, or thing. Animals, sunlight, and happiness are all examples.

Proper Noun

A proper noun is a name for a specific person, place, or thing that usually starts with a capital letter, such as Mahatma Gandhi, India , or World Cup.

Collective Noun

A collective noun, is a noun that refers to a group of people or things. It's not always clear whether a collective noun's verb should be singular or plural. Nouns like company, team, herd, public, and class, as well as the names of corporations, teams, and other entities, are singular in the United States, but multiple in the United Kingdom:
US - "The company has been doing great this year."
UK - "The company has been doing great this year."

Singular and Plural Noun

Singular nouns are nouns that exclusively refer to one thing:
For Example"Earth is the third planet from the Sun"
A plural noun, on the other hand, refers to more than one person or thing, or to something with two essential parts. Plural nouns have only one form and are used with plural verb forms:
For Example
"These scissors are old and rusted."
