This lesson covers the fundamentals and types of nouns, knowledge of which will help you in B-school entrance exams like the NMAT, SNAP and IIFT.

So, let’s get started!

Noun: A noun is a word that is used to name a person, animal, place, thing, or an abstract idea. Nouns tell you about the ‘what’s’ ‘who’s’ and ‘where’s’ of a sentence. Let’s see an example: TG and Dagny went to Maxims to order a chocolate truffle cake.

TG and Dagny are persons, Maxims is a place and chocolate truffle cake is a thing.

Nouns can be broadly classified into

  • Common nouns
  • Proper nouns
  • Concrete Nouns
  • Abstract Nouns
  • Countable Nouns
  • Non-Countable Nouns
  • Collective Nouns


  • Common Noun: A common noun is a noun that refers to a person, place or thing, in a general sense. Usually, you write a common noun with a capital letter only when a common noun begins a sentence.Go to the garden. (place)Pass me my phone. (thing)Call the police. (people)Milk the cow. (animal)
  • Proper Noun: A proper noun represents the name of a specific person, place or thing. The names of the days of the week, months, historical documents, institutions, organizations, religions, their holy texts and their adherents are all proper nouns. A proper noun begins with a capital letter irrespective of its placement in a sentence.Check out the following table to understand the difference between the two forms of nouns.



I donated most of my old clothes and headed to Benetton to buy some new ones.

clothes= common noun; Benetton= proper noun


Concrete Noun:

A concrete noun refers to a group of nouns that name anything or anyone that you can perceive through your five senses: touch, sight, taste, hearing, or smell.

Types of Noun

Example: Samantha enjoyed drinking her banana shake.

Here banana shake is a concrete noun. You can see, taste (yum!), smell, and touch the shake. Any noun that you can perceive with at least one of your five senses is a concrete noun.


Abstract Noun:

An abstract noun is a group of nouns that you cannot perceive through your five senses. It is the opposite of concrete noun.

Abstract Noun

Rohan got a bravery award this year for saving a small child from drowning.

Some examples of abstract nouns are : Love, hatred, loneliness, sadness, happiness, anger, ire, wrath, fun, education, courage, bravery, ability, talent, optimism, pessimism, luck, fortune, religion, valor, opportunity, faith, hope, contempt, duplicity, need, want, necessity, desire, wantonness, greed, lust, sympathy, affection, ardor, fondness, attachment, intimacy, worship, passion, emotion, joy, desperation, depression, disconsolation, regard, charity, goodwill, kindness, benevolence.


Countable Nouns: A countable noun represents the names of separate ideas, objects, people etc. that can be counted. You can use numbers or a/an before the countable nouns.

Rohan gave two chocolates to Sohan.

I saw three cats on the roof.


Uncountable Nouns:  A non-countable noun (or mass noun) represents people, places, things or ideas that cannot be counted. Non-countable nouns take singular verbs in a sentence and you cannot add a/an in the front or -s at the end of a non-countable noun.

Pass me a glass of water, please. (NOT a water or two waters)

We are planning to buy new furniture for our office. (NOT one furniture or a furniture)

Uncountable Nouns

There are some nouns that are usually uncountable in the English language, but are countable in other languages. These are examples:

accommodation, advice, applause, assistance, bread, baggage, camping, cash, chaos, chess, cloth, clothing, conduct, courage, cutlery, dancing, dirt, employment, equipment, evidence, fun, furniture, harm, health, homework, housing, information, leisure, litter, luck, luggage, machinery, money, mud, music, news, nonsense, parking, pay, permission, photography, poetry, pollution, produce, progress, publicity, research, rubbish, safety, scenery, shopping, sightseeing, smoke, software, sunshine, transport, violence, wine, weather, work.

Baggage, a non-countable noun, cannot have s/es in the end. You can, however, count the number of suitcases or bags you are carrying with yourself.

Often, we can make uncountable words countable by adding a prepositional phrase in front of it.

uncountable words

Sometimes the same word may have a slightly different meaning depending on whether it is used as a countable or non-countable noun.


I am going to buy some packing paper. (non-countable)

Where have you kept today’s paper? (a newspaper/ countable)

When you are happy, time flies by so quickly.  (non-countable)

I have reminded Anna at least three times to return my book. (countable)


Random stuff about countable and non-countable nouns.

  • News, groceries, customs, and thanks are uncountable nouns. They are not plural. E.g. This news is very important. I have bought the groceries (NOT a grocery)
  • Travel means ‘travelling in general’. You cannot say ‘ a travel ‘ to mean a journey or a trip. E.g. Have a happy journey. (NOT a happy travel)
  •  “on your travels’’, “in all weathers” are fixed expressions and are used in plural form. E.g. Did you meet anyone exciting on your travels? Dad goes to office in all weathers.
  • Hair is normally uncountable in English language. E.g. Her hair is black. But one strand of hair is a hair (countable). E.g. There are two hairs in your soup.
  • Tea, coffee, juice etc. (drinks) are normally uncountable. E.g. Coffee is my favourite drink. But drinks can be countable when you are thinking of a cup/ a glass etc. E.g. I would like to order two coffees. An apple juice, please.

Collective Noun: A collective noun refers to a group of things, animals, or persons. You can count the individual members in the group, but, usually a group considered as a whole is considered as one unit. Collective nouns can be used in both the singular form and the plural form. They are similar to a non-countable noun, and are roughly the opposite of a countable noun. Check out the chart below:

Collective Noun

People, things or animals can behave both as separate entities and collectively as a group; so the nouns can be either singular or plural, depending on the context.

How would you identify what verbs or pronouns would be used with collective nouns?

Case 1: Imagine a herd of buffaloes grazing in a grassland. What would happen when a lion races out of the bushes to attack the buffaloes? They would all run in one direction as one unit to save their lives. So when we talk of the collective noun as one unit, the noun becomes a singular entity and takes a singular verb and pronoun.

Collective Noun
Buffalo herd, Umfolozi Game Reserve, KZN, South Africa


The herd of buffaloes spends most of its time grazing the grass. (herd= singular; spends= singular; its=singular)

After an hour, the jury gave its verdict. (jury=singular; its = singular; all the members of the jury together acted as a single entity and gave a unanimous decision)

Case 2: Let’s imagine that the members of the jury have to come to a single conclusion but there were differences in opinions among the members of the jury. All of them had a different say. A jury is a group of people but all of them have a different opinion. They are not able to act as ONE. We can say:

Collective Noun

The jury were divided in their opinion.

After a long break, the faculty start their new research projects.

So when the members in a group are acting as an individual, the collective noun is plural and requires a plural verb.

Noun- Gender: The English language is pretty easy on categorizing people as ‘he’ or ‘she’ and things as ‘it’. Let’s take a look at these quick and easy points to remember.

  •  When you talk about animals, use ‘who’ instead of ‘which’. E.g. Sam had a parrot who used to speak.
  •  When you don’t know the sex of the person, use he/him/his. E.g. If he finds the person who created all the mischief, he is going to kill him. If you find the usage of he/him/his sexist, you can avoid that as well. Use he or she, him or her and his or her instead.  E.g. If he finds the person who created all the mischief, he is going to kill him or her.
  •  The noun that determines either the name of a male or a female is called a Common gender. E.g.  baby, child, cousin, enemy, friend, infant, monarch, neighbour, orphan, parent, pupil, person, relation servant, student, thief.
  •  Collective nouns, even if they refer to living-beings, are used as neuter-nouns. E.g. The team is going to play its game.
  •  Objects noted for their power, strength, and violence are used as Masculine gender nouns- The Sun, Summer, Winter, Time, Death e.g. Time is like the wind, he lifts the light and leaves the heavy.
  •  Objects noted for their beauty, gentleness and grace are used as Feminine gender nouns- the Moon, the Earth, Spring, Autumn, Nature, Liberty. E.g. Adopt the pace of nature:  her secret is patience.

Noun- Gender

There are three ways of forming a Feminine noun from the Masculine noun

  1. By adding a syllable (-ess, ine, trix, -a, etc.). E.g. host-hostess, poet- poetess, viscount-viscountess, conductor-conductress, tiger-tigress, hero-heroine, testator-testatrix, etc.
  2. By placing a word before or after. E.g. salesman-saleswoman, manservant-maidservant, landlord-landlady etc.
  3. By using an entirely different word. See the following chart.

Noun- Gender

Possessive Nouns

In a possessive case, a noun or pronoun changes its structure to talk about possessions, relationships, physical characteristics, especially when the first noun refers to the person, animal, country, organization or another group of creatures. Usually, nouns become possessive by adding a combination of an apostrophe and the letter “s”.

Examples:* Sam’s mother is a florist. (NOT the mother of Sam)

Rohan’s bike is new.

The company’s success depends on management’s values.

Following are the general structures that are followed to show possession.

Noun- Gender

Optional: If the noun is singular and ends with an s, add ‘s or add only the apostrophe (‘).

The bus’s tires went flat.

The bus’ tires went flat.

Dickens’ novels are read by young and old alike.

Dickens’s novels are read by young and old alike

Let’s see how an apostrophe’s placement can alter the meanings of the sentences:

Tom’s and Harry’s new books are available in the market.

This means that Tom and Harry wrote separate books and now the books are available in the market.

Tom and Harry’s new books are available in the market.

This means Tom and Harry together authored new books and now the books are available in the market.


Jack and Jill’s children are playing in the park.

This means that Jack and Jill are parents of the children.

Jack’s and Jill’s children are playing in the park.

This means that Jack’s children and Jill’s children are playing in the park.

Two separate lot of children playing in the park.

Possessive without a noun

*If the meaning is clear we can use the possessive without the following noun.

Whose book is this? It’s Rohan’s.

This is not my dress. It’s my sister’s.

*You can use ‘s with time expressions (yesterday/ next week/today/tomorrow/ Sunday/ Monday etc.)

Yesterday’s party got canceled.

Are you attending Monday’s conference?

He has got two weeks’ leave.

Noun + Noun Structure

*When we use noun + noun structure, the first noun is like an adjective. It is normally singular but the meaning is plural.

For example, a bookshop is a place where you can buy books; a tea bar is a bar where you can have tea.

Similarly, we say

a five rupee note (NOT five rupees note)

a night long journey (NOT nights long journey)

a five minute walk or five minutes’ walk (NOT five minutes walk)

  1. May I use your telephone?
  2. Do you have a spare toothbrush?
  3. Where have your kept my dictionary?
  4.  I want to write some notes but I haven’t got any paper.

 Divisibility Rules
A. Divisibility by 2, 4, 8, 16, 32.

A number is divisible by 2, 4, 8, 16, 32,.. 2 when the number formed by the last one, two, three, four, five…n digits is divisible by 2, 4, 8, 16, 32,..2 respectively.

Example: 1246384 is divisible by 8 because the number formed by the last three digits i.e. 384 is divisible by 8. The number 89764 is divisible by 4 because the number formed by the last two digits, 64 is divisible by 4.

B. Divisibility by 3 and 9

A number is divisible by 3 or 9 when the sum of the digits of the number is divisible by 3 or 9 respectively.

If a is a positive real number other than 1, and am = x, then we can write: m = logax, and we say that the value of log x to the base a is m.

(i) 104 = 10000     log10 10000 = 4.

(ii) 35 = 243     log3 243 = 5.

(iii) (0.1)3 = 0.001     log (0.1) (0.001) = 3.

It is uncanny how children pick up a lot of small habits and beliefs of their parents. Even the ones that rebel against their parents bear the subconscious resemblance to their father or mother. There is a lesson for instructors in this. It is important for them to realize that students mirror their feelings about CAT. If the instructor expresses or feels that CAT is tough, or is fearful about CAT, his students will mirror the same feeling and will be less confident. If the instructor is brazen and casual about the paper and scoffs the competition, his students would reflect the same feelings. Also, it is so necessary to have unflinching faith in one’s students. I still remember that during my school days my mother used to proudly proclaim that I was an intelligent kid. I was barely scrapping passing marks in the school exams. If truth be told I was at the bottom of the class, but my mother had her blinkers on. And because of my mother, I also believed that I was second to none. It was only years later, during my boards exams, that I took to studying seriously, and managed to outperform everyone else. I don’t know if it was my mother’s blind love for me or that she could see some bright spark in me that made her claim my intelligence but it really had great effect on my attitude. And attitude, in an exam like CAT, is everything.

Well, it’s almost everything. A keen attitude towards CAT subjects’ fundamentals also plays an important role in one’s performance.
