Punctuation is using special signs, and certain typographical devices to help the understanding and correct reading of written texts.

Punctuation Marks in English

What Is Punctuation?

Punctuation is the use of standardized marks and symbols in writing to clarify meaning and indicate the structure and organization of sentences. Punctuation is a crucial aspect of written communication as it helps to convey meaning and prevent ambiguity.

Common Punctuation Marks

Here is a list of common punctuation marks in English:

Full Stop

Full stop is also called period in American English. it is a punctuation sign that is used at the end of a statement or in some abbreviations. Keep in mind that there is no space before full stop and one space after it.


There are three kinds of abbreviations:

  1. Abbreviations with no full stops, like CIA, CNN, MTV
  2. Abbreviations that always have a full stop, like e.g., i.e., or etc.
  3. Abbreviations that sometimes have a full stop, like Mr./Mr a.m./AM Dr./Dr

In British English, titles and honorifics are usually written without full stops. But in American English, they are written with full stops.
British English usually uses a.m. and p.m. in lowercase and with full stops. In American English, however, they are written with uppercase letters and without full stops (AM and PM). They both are correct and you can use them according to the variety of English you are using.

I know you well.

She wakes up at 5 a.m. everyday.

Mr. Johnson is on his way to the office.

Question Mark & Exclamation Mark

Question mark (?) is used at the end of a direct question whether it is a wh-question or a yes/no question. The direct question is a sentence that asks a question directly from the addressee. For example:

Where are you?

Are you ok?

An exclamation mark (!) is used in at the end of a sentence expressing strong emotions such as anger, surprise, joy, etc. Notice that what and how are commonly used at the beginning of a sentence to make an exclamatory phrase.

Oh no! I can't believe it!

What a mistake!

How stupid you are!


Commas are used for three main purposes:

  1. To separate items on a list
  2. Before certain conjunctions (and, but, so, or)
  3. To add non-essential information

To Separate Items on a List

We use commas to separate items on a list. To introduce the last item on the list, the comma is followed by an 'and'.

I have bought some rice, milk, bananas, and bread.

We need to take water, fruits, sleeping bags, canned food, and tent for camping.

using comma to separate the items of a list

Before Certain Conjunctions

We can use commas before certain conjunctions: 'and', 'but', 'so', and 'or'.
Take a look at the examples:

You can tell her, but she'll get upset.

This was his last chance, so he took it.

To Add Non-essential Information

We can use a comma, or sometimes two commas, to separate non-essential information from the rest of the sentence. Non-essential information can be removed from the sentence without changing its overall meaning. For example:

Usually, I go to school.

Apparently, he was a very good painter.

Beijing, which is the capital of China, has a mixture of modern and ancient architecture.

Commas can be used for many other purposes. They are used in dates and numbers, after adverbs, in direct reported speech, and between adjectives. You can see some examples below:



April 1st, 1999, she left him.


He said, "I am not going to do that."

in direct reported speech

There was a big, fascinating, marvelous wedding there.

between adjectives

Colons & Semicolons

Colons (:) are used to introduce examples, explanations, or details. The main idea is expressed before the colons and the explanation or examples appear right after it. Colons can be used to introduce a list, a dialogue, a title, or to show emphasis.

The power outage has caused many problems: darkness, burnt out electric devices, transportation disruption, and so on.

Here, the general idea is the power outage problems, and after the colons we can see the explanations or examples.

I can be sure of one thing: she won't let you to get a dog.

show emphasis

What we need for the cake is: butter, flour, water, etc.

introducing a list

She played: 3GA.

introducing a title

Semicolons (;) are similar to a full stop in that they are both used at the end of a full sentence. But the difference is that the semi-colon shows that the sentences before and after the semi-colon are connected and express the same idea. For example:

The weather is so hot; it's impossible to get out of the house without getting a heatstroke.

As you can see in the example, semicolons are used to join two independent clauses. They can also appear:

  1. Before conjunctive adverbs, like 'however', 'thereafter', 'therefore', etc.
  2. Before coordinating conjunctions, like 'but', 'or', 'and'.

We couldn't go; however, we really wanted to.

conjunctive adverbs

We were looking for what they called us for; and the result was disappointing.

coordinating conjunctions

Quotation Mark

Quotation marks ('' ") are used when reporting a direct speech. They are also used to avoid repetition in a list. There are two kinds of quotation marks: single (‘) and double (“). They are usually used interchangeably. But in some cases, it’s better to use one of them in particular. For example, it’s better to use double quotation marks when you are quoting what someone said.

He laughed and said, “you’ll kill me with these jokes”.

She asked," Who is the lead actor."

direct speech

Here is another example of how quotation marks are used to avoid repetition:

names of fathers
Steve Max
Rhone ''
Mia ''

When we want to put emphasis on a word or phrase in a sentence, we use single quotation marks. For example:

This is a sentence where the 'adverb' plays the central role.

We can also use the quotation mark to indicate irony, skepticism, and sarcasm. For example:

My “friends” left me there all alone.

Here, "friends" in quotation marks to indicate irony because they did not act as real friends.

The “clean” sheets smelled like mold.

You can also use quotation marks when the words are not used in their literal meaning.

The TV ‘knows’ when I have homework, it starts playing all the good shows.

Clearly the TV cannot know anything, it's used metaphorically.

You can use quotation marks when you refer to words as ‘words’ and not for what they mean. For example:

How do you spell ‘whitening’?

We don't use the word for what it means and we show it by using the quotation marks.

Hyphens & Dashes

Even though hyphens and dashes look a lot alike, they are different and serve different functions.


We have two kinds of dashes: en dashes (–) and em dashes (—).

  • En dashes (–) are used to replace the words like "and", "through", and "to" when indicating numerical ranges, describing directions, relationships, or scores

The world war one (19141918) was a great disaster.

Sometimes, in British English, the en dash does the same thing as the em dash. In these cases, there are spaces on both sides of the en dash to add extra information to the sentence. Commas can be used for this purpose too, but dashes are preferable when the information we are adding doesn't fit well in the sentence.

Jeff – who is my best friend – already went back home.

  • Em dashes (—) work like parenthesis and commas, they add non-essential information to the sentence and this usually happens when the information we are adding doesn't fit well in the sentence. The em dashes can be used with space on either side or without spaces.

My best friend—who I haven't seen in years—got married yesterday.

Years ago — never mind how long precisely — I thought I could run all around the globe.

We can also use dashes when repeating an emphatic part or phrase in a sentence. In this case, we can use a dash at the beginning of the emphatic part. Check out these examples:

The beautiful sky—the clear blue sky—was her dream.


The first thing about hyphens (-) is they are not the same as dashes (– and —). Hyphens are used to:

  • form compound modifiers before a noun

It is a short-term plan.

I went for a full-body massage.

  • form compound adjectives with nouns

Why are you wearing these old-fashioned clothes?

Have you seen that six-feet girl?

I saw my ex-wife yesterday.

She is a self-made girl.

  • enhance clarity and readability of sentences

I will re-design the whole place.

meaning to design again

They wanted to re-elect him.

instead of writing 'reelect' which is hard to read.

Brackets, Braces, & Parentheses

There are four types of brackets:

  1. square brackets [ ]
  2. curly brackets { } or braces
  3. angle brackets < >
  4. round brackets or parentheses ( )

Square brackets are used to add Information, comments, or definition in a sentence:

They said the [cancer] patients are not satisfied with the services.


We need a doctor [an expert] to do the surgery.


The indolent [lazy] man spent all day at home.


Braces are usually used in mathematical, chemical, and statistical equations.

2{1 + [32 + 3]}

Round brackets or parentheses are used for two purposes:
1. Give Information (date/answer/statistics).
2. Set off numbers and letters (give options).

The doctors did what was possible (they couldn't do more).

Giving Information

The world war one (1914–1918) was a great disaster.


Remember to take: (1) pen (2) ruler (3) hair brushes.

Three items are needed: pen, ruler, hair brush

Write your opinion(s) here.

the reader can choose how to read it.


Try to avoid using parenthesis to add long ideas in your sentences, for that purpose you can use commas or dashes accordingly.


Apostrophe (') is used in two cases:
1. Create contracted forms
2. Form possessive nouns

Isn’t → is not

contracted form

Sarah's father

possessive nouns


We can never use an apostrophe to make plurals, unless we are referring to multiple letters. For example:

How many M’s are there in ‘common’?
