A noun (from Latin nōmen 'name') is a word that functions as the name of a specific object or set of objects, such as living creatures , places, actions, qualities, states of existence, or ideas.However, noun is not a semantic category, so it cannot be characterized in terms of its meaning. Thus, actions and states of existence can also be expressed by verbs , qualities by adjectives , and places by adverbs. Linguistically , a noun is a member of a large, open part of speech whose members can occur as the main word in the subject of a clause, the object of a verb , or the object of a preposition. Many different types of nouns exist, including proper and common nouns, collective nouns, mass nouns, and so forth.
Compound Nouns
A compound noun is a noun that is made with two or more words. A compound noun is usually [noun + noun] or [adjective + noun], but there are other combinations. It is important to understand and recognize compound nouns.
Noun as Adjective
Sometimes we use a noun to describe another noun. In that case, the first noun "acts as" an adjective.
Possessive
When we want to show that something belongs to somebody or something, we usually add an apostrophe + s ('s) to a singular noun and an apostrophe (') to a plural noun
Plural-Only Nouns
There is a small group of nouns that exist only in the plural form, for example:clothes, pants, scissors, shorts, thanks, trousers
Collective Nouns
A collective noun is a noun that represents a collection of individuals, usually people,
Proper Nouns
A proper noun is the special word that we use for a person, place or organization, like John, Marie, London, France or Sony. A name is a noun, but a very special noun - a proper noun. English proper nouns have special rules.
Common Nouns
Common nouns can be countable (bottle, dollar) or uncountable (milk, money); singular (desk, pencil) or plural (desks, pencils); concrete (piano, bed) or abstract (music, happiness). And they follow all the usual rules of countable/uncountable, singular/plural, concrete/abstract nouns.
Uncountable Nouns
Unlike countable nouns, uncountable nouns are substances, concepts etc that we cannot divide into separate elements.
Countable Nouns
The major division of English nouns is into "countable" and "uncountable".
Types of Nouns
Nouns are an important part of speech in English, probably second only to verbs. It is difficult to say much without using a noun.
