Noun and it's types.

What is a Noun?
A noun is defined as a word that names or identifies a person, place, thing, idea, or animal.
Nouns are the words in a sentence that represent a certain person (John), place (London), thing (pen), idea (discipline), or animal (dog). Nouns can be concrete (pen) or abstract (discipline).
The easiest way to spot a noun is by identifying a name, place, thing, idea, or animal in a sentence.
Being aware of the noun definition, noun meaning, and what are nouns is integral for understanding grammar and sentence structure in any language.

Types of nouns
Proper noun
Proper nouns are nouns that specifically name a person, place, or thing. Proper nouns start with capital letters, making it easy to distinguish them from other types of nouns.

Collective noun
A noun used to refer to a group of individuals, animals, or things as a single unit is called a collective noun. It shows a grouping of similar things. Collective nouns are a type of singular noun but they represent a plurality of items.
Common noun
A noun that refers to a general category of people, places, or things is called a common noun. Common nouns do not represent a particular category or specific instance.
Abstract noun
A word that represents an idea, a state, or an intangible concept is called an abstract noun. Abstract nouns are things that cannot be seen or touched physically but are present as feelings or emotions. Abstract nouns refer to things that are intangible and exist as feelings, thoughts, and ideas.
Concrete noun
A concrete noun is a type of noun that refers to tangible objects that can be felt or perceived physically using their senses. Unlike abstract nouns, concrete nouns can be seen, touched, heard, and experienced physically.
Plural noun
A plural noun is used to indicate more than one of a place, thing, person, animal, or idea. Plural nouns are represented by words that are made plural by adding ‘s’, ‘es’, or ‘ies’ to the ending. Confusing plural nouns with collective nouns is one of the common grammatical mistakes people make. Plural nouns refer to multiple individuals or objects while collective nouns refer to a group or collection of individuals or objects.
Possessive noun
A possessive noun is a word used to indicate ownership or possession of something. It shows possession or that something belongs to someone. It is often formed by adding a ‘s at the end of the words which show that the noun owns or possesses something.
Compound noun
A noun that is formed by combining two or more words to create a new, single noun is called a compound noun. The combination of these two or more words results in the formation of a new word having a distinct meaning. The three types of compound nouns that are commonly used are hyphenated compound nouns, closed compound nouns, and open compound nouns.
Countable nouns
Countable nouns are people, objects, places, things, and ideas that can be counted using numbers. These nouns have plural forms.
Uncountable nouns
Uncountable nouns are those objects and ideas that cannot be counted using numbers. This means that the individual units of these nouns cannot be counted. These nouns do not have plural forms. Words such as some, any, much, and enough can be used to describe the quantity of these nouns. 

Appositive nouns
Nouns that are used to add specificity or additional context to a noun in the sentence are known as appositive nouns. Appositive nouns give extra information about the subject and make sentences more engaging. They are typically set off by commas, dashes, or parentheses.
