Punctuation
Definition of Punctuation
Punctuation is the system of symbols used in writing to separate
sentences and clarify meaning. It helps readers understand the structure and
flow of the text by indicating pauses, stops, or emphasis.
For example:
- Let's eat, Grandpa!
(with punctuation – means calling Grandpa to eat)
- Let's eat Grandpa!
(without proper punctuation – sounds like eating Grandpa!)

Uses of Semicolon ( ;
) in English
A semicolon ( ;
) is a punctuation mark used to connect closely related ideas or
separate items in a complex list. It shows a stronger pause than a
comma but not a full stop.
1. To Join Two Closely
Related Independent Clauses
Use a semicolon to connect
two complete sentences that are closely related in meaning but not
joined by a conjunction (like "and" or "but").
Examples:
- I went to the market; it was already closed.
- She loves to paint; her brother prefers photography.
Note: Both sides of the semicolon must be
complete sentences (independent clauses).
2. To Join Independent
Clauses with a Conjunctive Adverb or Transitional Phrase
When using words
like however, therefore, otherwise, meanwhile, nevertheless,
consequently, etc., to link two independent clauses, use a semicolon
before the linking word and a comma after it.
Examples:
- He was very tired; however, he continued working.
- It rained heavily; therefore, the match was canceled.
- She didn’t study; consequently, she failed the test.
3. To Separate Items in
a Complex List
Use semicolons to
separate items in a list when the items themselves contain commas.
Examples:
- We visited Kathmandu, Nepal; Delhi, India; and Bangkok,
Thailand.
- The candidates were Ramesh Shrestha, teacher; Sita
Pandey, doctor; and Hari Karki, engineer.

Uses of Colon ( : ) in English
A colon ( : ) is a
punctuation mark used to introduce lists, explanations, quotations, or
emphasis. It signals that what comes next is directly related to the
previous part of the sentence.
1.
To Introduce a List
Use a colon after a complete
sentence to introduce items in a list.
Examples:
- You need to bring the following: a pen, a notebook, and
a calculator.
- She bought three things: shoes, a bag, and a dress.
Note: Don’t use a colon directly after a verb or preposition
unless the sentence is complete.

Use a colon to introduce a reason,
explanation, or elaboration.
Examples:
- He got what he deserved: a long prison sentence.
- There’s one thing you need to remember: always tell the
truth.

When a complete sentence introduces
a quotation, use a colon before the quote.

Uses of Dash ( — ) in English
A dash (—) is a punctuation
mark used to create emphasis, add extra information, or show a sudden break in
thought. It is longer than a hyphen (-) and should not be confused with it.
There are two main types:
- Em dash (—):
Commonly used in writing (long dash).
- En dash (–):
Used for ranges (e.g., 2010–2020).
Below are the main uses of the em
dash (—):
1.
To Add Extra Information or Explanation
Used like parentheses or commas to
add extra, non-essential information in a sentence.
Examples:
- My brother — who lives in Canada — is a doctor.
- The car — a red Toyota — is parked outside.

To Show a Sudden Break or Interruption
Used to indicate a sudden change of
thought or an unfinished sentence.

end of a sentence.

4.
In Place of a Colon (for Emphasis or Explanation)
An em dash can replace a colon to
introduce a list or explanation, especially in informal writing.
Examples:
- She brought everything she needed — books, pens, and
snacks.
- He got what he deserved — a second chance.
5.
To Indicate Interrupted Dialogue (in Stories or Scripts)
Used to show that a character is cut
off or interrupted.
Example:
- “But I thought you said—”
Uses of Hyphen ( - ) in English
A hyphen (-) is a short
punctuation mark used to join words or split words at the end of
a line. It is not the same as a dash (—), which is longer.
1.
To Form Compound Words
Hyphens are used to connect two
or more words that act as a single idea (compound adjectives or compound
nouns).
Examples:
- My father-in-law is visiting.
- She bought a well-known brand.
- He is a full-time employee.
2.
To Avoid Confusion or Misreading
A hyphen helps clarify the meaning
of certain combinations of words.
Examples:
- Re-sign (sign again) vs. Resign (quit a job)
- Co-op (cooperative) vs. Coop (chicken house)
3.
With Prefixes and Suffixes
Some words with prefixes or suffixes
need a hyphen, especially when:
- The root word is capitalized.
- There’s a repetition of the same vowel.
- To avoid ambiguity.
Examples:
- ex-president
- re-enter
- anti-American
- self-esteem
4.
To Indicate Word Division at the End of a Line
In writing, a hyphen can split a
word that doesn’t fit on one line (less common in digital writing now).
Example:
- The children were enjoy-
ing their summer vacation.
5.
In Numbers and Fractions (as adjectives)
Used in number words or when
fractions are used as adjectives.

- A two-thirds majority is required.

Uses of Interrogative Sign / Question Mark ( ? )

punctuation mark used at the end of a sentence to indicate a direct question.

question.
Examples:

When the sentence offers a choice
between two or more options.

an actual answer, it ends with a question mark.

In Questions within Quotations
If a quoted sentence is a question,
the question mark goes inside the quotation marks.

longer sentence, only the question part gets the question mark.
