A Noun is a naming word. A noun is a word used to name something: a person/animal, a place, a thing, or an idea. For example, all of the following are nouns.
1. Proper nouns
2. Common nouns
3. Collective nouns
4. Material nouns
5 Abstract nouns
1. Proper Nouns: A proper noun is the name of a particular person, place or thing. For example, “London” is the name of a particular city and “History” is the name of a particular subject. Think of the other proper nouns in the passage. A proper noun usually begins with a capital letter. A proper Noun is usually singular but some proper nouns are plural in form.
2. Collective Noun: These are nouns that refer to a group of things. Army, Council, Audience, department, minority, board, faculty, navy, crowd, family, senate, class, farm, society, committee, group etc.
3. Common Noun: A common noun refers to every person, place or thing of the same class or kind. It does not refer to anything in particular. For example, the noun ‘boy’ may mean any boy in the world. A common noun can be both singular and plural. For example, London is a big city. There are many big cities in the world. Note: A proper noun can be used as a common noun. Look at the following examples: He is called the Shakespeare (= the greatest dramatist) of U.S.A. There are two Johns in this class.
4. Collective Nouns: A collective noun is the name of a collection or group of people or things taken together. For example, an army is a group of soldiers and a team is a group of players. Think of the other nouns in the passage as a group of persons spoken of as one whole. A collective noun can take both singular and plural verbs after it. For example, The governments has/have decided on a new pay scale. The committee was/were in favour of my proposal.
5. Material Noun: A material noun names a thing that has weight but cannot be counted. It is a kind of mass noun which is considered uncountable. It refers to any material or substance. The substance may be solid, liquid or gaseous. “Oxygen” is also a material noun.
Material Nouns From Animals: Egg, Meat, Honey, Milk, Silk, Leather, Wool, etc.
Material Nouns From Plants: Cotton, Food, Oil, Wood, Jute, Coffee, Medicine, Tea, Rubber, Perfume, etc.
Man-Made Material Nouns: Acid, Alcohol, Asphalt, Brick, Cement, Butter, Chalk, Ghee, Cheese, Dacron, Ebony, Enamel, Felt, Gelatin, Paraffin Cloth etc.
6. Abstract Noun: An abstract noun is the name of a quality, state or concept. It has no material form, shape or size. For example, Hassan is s a kind man. He has love and sympathy for the poor class of people.
1. Countable Noun
2. Uncountable Noun
ii. A collection of 100 songs.
2. Uncountable Noun: Uncountable nouns are words that represent things we do not count. For example, the word music is an uncountable noun. Here are some examples:
i. A lot of music
ii. The music of the 70s.
Now, let's look at countable and uncountable nouns in more details.
ii. I want five oranges? - Here five is used to count the number of oranges.
i. A good book
When a countable noun is singular, we must use a word like a/the/my/this with it:
i. I want an orange. (Not I want orange.)
ii. Where is my watch? (Not where is watch?)
iii. We can use some and any with countable nouns:
iv. I've got some coins.
v. Have you got any pens?
We can use a few and many with countable nouns:
i. I've got a few coins.
ii. I haven't got many pens.
Now, in the above examples you must have noticed the way plural nouns are formed.
B. Plural
i. The furniture was new. (Furniture is an uncountable noun and therefore, we use the singular 'was' in referring to it.)
ii. Is 250gm of sugar enough (Sugar is an uncountable noun as sugar itself cannot be counted. It can only be weighed.)
iii. He is praised for his honesty. - Honesty is an uncountable noun as it has no plural and cannot be counted in physical terms either.
