A noun is a part of speech that names a person, place, thing, idea, action or quality.
A noun is a part of speech, which is just a fancy way of saying, word. Hence, it can be said that noun is a specific type of word. It can be used to refer to the name of some specific thing or set of things. For example, glass or glasses, pen, pens, utensil, bottle, mat, etc.
Noun can also be used to refer to living creatures, objects, places, actions, qualities, states of existence, or ideas. For example, John, Mary, Paris, London, America, assignment, newspapers, beauty, wonder, etc.
There are two main types of nouns: proper nouns and common nouns.
Proper nouns are the proper names of people or places. For example, John, Mary, Peter, Tom, London, Tokyo, Japan, India, etc. These types of nouns must be written in capital case or upper case.
Common nouns are the regular everyday names of things. For example, place, country, man, woman, city, mat, pen, pencil, cup, plate, etc. These types of nouns must be always written in capital case or lower case.
Nouns are an important part of any language, so much so that there couldn’t be a language without it. In fact our ancestors started language by starting to name things. These names were and are nouns. Nouns are the main word in the subject of a clause, the object of a verb, or the object of a preposition.
