Punctuation is a set of standardised symbols and signs used to express meaning, structure and clarity in written language. Commas, periods, semicolons, colons, exclamation points, question marks, hyphens, brackets and other symbols are among them.
Punctuation is important in higher-level communication for several reasons:
→ It aids in defining sentence boundaries, separating ideas and distinguishing between different sentence elements.
→ It can emphasise specific words or phrases, influencing the reader's interpretation.
→ It guides the reader's pace and rhythm while reading, enhancing the flow of the text.
→ Punctuation can condense complex ideas into succinct, meaningful units.

1. Semicolon (;): The semicolon is used to connect two independent clauses that are closely related, providing a stronger connection than a comma alone.
Example: Shelly studied for hours; nevertheless, she couldn't grasp the concept.
2. Em Dash (--): The em dash is used to indicate an abrupt change in thought or to add emphasis to a statement. It's longer than a hyphen.
Example: The storm raged outside -- howling winds and torrential rain making it impossible to see beyond the window.
3. Colon (:): A colon is used to introduce a list, an explanation or a quotation that elaborates on the preceding statement.
Example: There were three reasons for his success: dedication, perseverance and a touch of luck.
4. Apostrophe ('): An apostrophe is used to indicate possession or to form contractions. For example, can't for cannot.
Example: The cat's tail twitched with irritation.
5. Quotation marks: Quotation marks are used to indicate direct speech or to enclose titles of short works like poems, short stories, or articles.
Example: "To be or not to be, that is the question," pondered Hamlet.
6. Hyphen: A hyphen is used to join words together, often to form compound words or to indicate a range of values.
Example: It was a well-known fact that the time-sensitive project required immediate attention.
7. Question mark: A question mark is used at the end of a sentence to indicate a direct question.
Example: Are you sure you want to proceed with this decision?
The following table summarises the key differences and usage of the colon, semicolon and comma:
Punctuation Mark |
Use |
Example |
Colon (:) |
→ introduces a list, explanation or elaboration of the preceding clause. → used before a list, quote or summary. → used to separate a title from a subtitle. |
→ There are three primary colours: red, blue, and yellow. → She quoted Shakespeare's famous lines: "To be or not to be." → The book is titled "The Art of War: Strategies for Success." |
Semicolon (;) |
→ connects two closely related independent clauses. → separates items in a list when the items themselves contain commas. |
→ Shelly loves hiking; Jack prefers cycling. → The team members included Sarah, the project manager; John, the lead developer; and Lisa, the designer. |
Comma (,) |
→ separates items in a list. Joins two independent clauses when used with a coordinating conjunction (e.g., and, but, or). → sets off introductory elements, non-essential clauses and phrases. |
→ John needs to buy eggs, milk and bread from the store. → I wanted to go to the party, but I had too much work. → After the rain stopped, we went for a walk. |
There are three main types of sentence structures: complete sentences, sentence fragments and run-on sentences. Let's explore the differences:
→ A complete sentence also known as an independent clause, is a group of words that expresses a complete thought or idea.
→ It typically consists of a subject (who or what the sentence is about) and a predicate (what the subject is doing or what is happening).
→ A complete sentence must be punctuated with a period (.), an exclamation mark (!), or a question mark (?) at the end.
→ For example, Jack loves to read mysteries.
→ A sentence fragment is an incomplete group of words that does not express a complete thought or idea.
→ It may lack a subject, a predicate or both.
→ Sentence fragments often result from incomplete thoughts or missing components.
→ For example, running in the park (Here, in this sentence, it lacks a subject such as "I am running in the park")
→ A run-on sentence occurs when two or more complete thoughts or ideas are combined into a single sentence without appropriate punctuation or coordinating conjunctions to separate them.
→ Run-on sentences can be overly long and confusing.
There are two main types of run-on sentences:
1. Comma splice: Where two complete thoughts are separated by a comma but no coordinating conjunction.
For example, I went to the store, bought some groceries.
2. Fused sentence: Where two complete thoughts are simply combined without any punctuation.
For example, I went to the store I bought some groceries.
To correct run-on sentences, the following methods can be used:
→ Use a period to create two separate sentences.
→ Use a semicolon to connect related thoughts.
→ Use a coordinating conjunction (e.g., and, but, or) with a comma to link two independent clauses.
→ Use a subordinating conjunction to turn one of the clauses into a dependent clause.
Ellipses are used in writing for various purposes, such as indicating a pause, omission of words or creating suspense. Generally, it is represented by three consecutive dots (...).
Let's understand its usage through some examples:
Indicating a Pause: Sussain looked out the window, lost in thought...
Omission of Words: The recipe called for sugar, flour, eggs and vanilla extract... but she couldn't find the chocolate chips.
Creating Suspense: The shadowy figure approached, and then, in a whisper, said, "I know your secret..."
Trailing Off in Speech: I thought we were going to meet at the cafe, but then I got caught up with work, and I..."
Indicating Ongoing Thought or Uncertainty: I think I left my keys in the car somewhere..."
