Punctuations English Grammar

What is Punctuation?

Punctuation is a system of using certain pauses and stops to organise one’s writing. 

Why Use Punctuation?

  • Let’s eat grandma!
  • Let’s eat, grandma!

Punctuation matters. When you read the first sentence above, it actually means that grandma is going to be eaten by someone. Thank God for the comma in the second sentence. It makes it clear that the writer only meant to call grandma to have their meal together. Indeed, punctuation saves lives! 

This chapter has been divided into two parts—basic punctuation and advanced punctuation. In this section, we will look at some basic punctuation marks. 

Basic Punctuation

Some punctuation marks are more commonly used than others. For instance, you will notice a comma and a full stop appearing more often (like in this sentence) than the other punctuation marks. In this section, we will examine and understand the use of

  • Full stop
  • Capitalisation
  • Question mark
  • Exclamation mark
  • Quotation marks
  • Comma

Full stop (.)

A full stop is primarily used to mark the end of a sentence

  • Kirti loved to play badminton with her friend on Sundays.  
  • Harshad wanted to score a 100% in his aptitude test.    

Exception: A full stop is not used to end exclamatory sentences and questions. 

  • The full stop is also used after abbreviations, titles, names and degrees. However, rules regarding this usage vary with British and American English. 

If the abbreviation consists of the first and the last letters of the word, do not put a full stop.

  • British English: Dr, St, Mr, Mrs, Ms, MA, PhD
  • American English: Dr., St., Mr., Mrs., Ms., M.A., Ph.D.

If the abbreviation is only the first part of the word, use a full stop.

Prof. Paul asked us to go to the laboratory in the afternoon. 

The full stop is also used when writing time in the British English convention.

  • British English: 11.23 a.m., 05.45 P.M.
  • American English: 02:30 am, 10:15 PM


Never capitalize unless necessary. The rules below will help you decide when to use capitalisation.

Advanced Punctuation

What is Punctuation?

Punctuation plays an important role in organising your written content. In the chapter on basic punctuation, you studied about using the full stop, the exclamation mark, the question mark, the comma, quotation marks and capitalisation. In this chapter, we will study and understand the use of Brackets

  • Semicolon
  • Colon
  • Apostrophe

Brackets ( ) [ ]

Round brackets ( ) are used to include non-essential information in a sentence. They are also called parentheses. o The Etruscan shrew (1.2 to 2.7g) is considered the world’s smallest mammal.

Round brackets are also used to enclose comments of the writer.  o The teacher was being strict (unlike her usual self) even with the most obedient student in the class.

Square brackets [ ] are used for clarification and addition of information. o They eventually decided to ask them [the guests] about the stolen diamond.

o She [Helen Keller] was the first deaf–blind person to earn a Bachelor of Arts degree. 

Semicolon (;)

A semicolon marks a stronger pause than a comma but is weaker than a full stop. 

A semicolon is used 

Between independent clauses where coordinating conjunctions are omitted o The stepmother allowed her children to go to the ball; Milinda was asked to stay at home and complete the chores. 

Between independent clauses set off by transitional elements o Militants continue to wreak havoc in the lives of civilians in J&K; consequently, the Indian Army has decided to take extreme steps to curb the violence.

In lists with internal commas o The new hotel will have a rooftop Jacuzzi; a Thai spa, an Ayurveda centre and a reflexology centre in the east wing; recreational and kids play area in the southern wing; library and meditation centres in the west wing; and a virtual gaming zone in the north wing.

In combination with a comma in elliptical constructions o Last November, Chitra was wondering if her two-year old daughter was ever going to talk; today, the little girl is a terror and doesn’t keep quiet even for a minute. 

o Some people brought food; others, money; yet others, merely loitered around in search of gossip.

Colon (:)

A colon is used 

To introduce a list after an independent clause o The institute offers three courses: Vedic Mathematics, Vocabulary Building and Improving Communication Skills.

Do not use a colon when the listed items are incorporated into a simple sentence.

  • Correct: The institute offers courses in Vedic Mathematics, Vocabulary Building and Improving Communication Skills.  o Incorrect: The institute offers courses in: Vedic Mathematics, Vocabulary Building and Improving Communication Skills.

Between independent clauses when the second explains or illustrates the first o Priti has no time to buy a new dress for the wedding: she had to catch a flight in two hours.

  • All three of her grandchildren are involved in philanthropy: Bernard heads an NGO, Jasmine donates 20% of her annual income to UNICEF and William teaches blind children for free.

To introduce a quotation after an independent clause o My sister’s reaction after I told her that I would leave for London for higher studies: “Fare thee well, Sir!”

Apostrophe (’)

An apostrophe is used 

To show possession o Omars idea was stolen by the rival team and presented at the conference. 

  • The twins health was envied by every visitor so much so that the parents feared they would fall ill. 

To show time period o The committee asked for a weeks time to submit their report. 

To show omission in contractions  o Its a beautiful day.

  • It is a beautiful day.
  • Theyd spend days at the farm working with Uncle Henry and helping him take care of the farm animals.  o They would spend days at the farm working with Uncle Henry and helping him take care of the farm animals. 
  • Theres a sale on new books in the store in the next building.  o There is a sale on new books in the store in the next building. 


The word   it’s doesn’t refer to a possessive form. The possessive form is its and it doesn’t take an apostrophe.

  • The car wasn’t looking bright red anymore. Its colour had started to fade in the sunlight.
  • This is my car. It’s an SUV.  (it’s = it is)
