Noun
A noun is a word that refers to a thing (book), a person (Noah Webster), an animal (cat), a place (Omaha), a quality (softness), an idea (justice), or an action (yodeling).
There are common nouns and proper nouns.
A common noun refers to a person, place, or thing but is not the name of a particular person, place, or thing. Examples are animal, sunlight, and happiness.
A proper noun is the name of a particular person, place, or thing; it usually begins with a capital letter: Abraham Lincoln, Argentina, and World War I are all proper nouns.
A collective noun is a noun that names a group of people or things, such as flock or squad. List
Gerunds are nouns that are identical to the present participle (-ing form) of a verb, as in "I enjoy swimming more than running."
An attributive noun is a noun that modifies another noun that immediately follows it, such as business in business meeting. These nouns look like adjectives but they're not.
A count noun is a noun that can be used after a or an or after a number (or another word that means "more than one").
A mass noun (or noncount noun) refers to something that cannot be counted.
Nouns which only ever refer to one thing are called singular nouns: "Saturn is the sixth planet from the sun," "We heard a terrible din in the alley." And a plural noun refers to more than one person or thing, or sometimes to something that has two main parts.
Abstract Nouns – An abstract noun is used to name something you cannot detect with your physical sense. It is basically an idea or a feeling that exists in our mind and needs a name or a description. Unlike the other nouns, which are often called concrete nouns, an abstract Happiness was something that was missing from his life.
