Semicolons (;) are one of the most misunderstood punctuation marks in English. Many writers avoid them altogether, while others overuse them. But learning when to use a semicolon can make your writing clearer, stronger, and more professional. This guide breaks it down simply—with examples you can follow.
When to Use a Semicolon in a Sentence
I. To Connect Related Independent Clauses
A semicolon can join two complete sentences that are closely related.
Example:
I love writing; it helps me express my creativity.
Each part could stand alone as its own sentence, but the semicolon shows they’re strongly connected.
When to use a semicolon instead of a period:
If the ideas are closely linked and you want to show that connection, use a semicolon. If not, a period is better.
II. Before Transitional Words (However, Therefore, etc.)
When two complete sentences are joined by a word like however, therefore, or moreover, use a semicolon before the transition word and a comma after.
Example:
She wanted to go for a run; however, it started raining.
Without the semicolon, this would be a grammar mistake called a comma splice.
When to Use a Semicolon in a List
If a list has items that already include commas, semicolons help keep things clear.
Confusing Example (❌):
The conference attendees included Dr. Smith, a biologist, Jane Doe, a journalist, and Mark Lee, an engineer.
Clear Version (✅):
The conference attendees included Dr. Smith, a biologist; Jane Doe, a journalist; and Mark Lee, an engineer.
Here’s another one:
Example:
Our team includes John, the designer; Sarah, the developer; and Mark, the writer.
More Examples of When to Use a Semicolon
- Joining related sentences:
I have a big test tomorrow; I need to study tonight. - Before transition words:
He wanted to buy the car; however, it was too expensive. - In complex lists:
We visited Paris, France; Rome, Italy; and Barcelona, Spain.
When Not to Use a Semicolon
- ❌ With coordinating conjunctions (and, but, or):
✔ I wanted to go, but it was raining. - ❌ Before a dependent clause:
✔ Because I was tired, I went to bed.
Final Tip for use of Semicolon
Use a semicolon when:
- ✅ You’re linking two related, complete sentences.
- ✅ You’re listing items with internal commas.
- ✅ You’re using transition words like however or therefore.
Still unsure when to use a semicolon? Read your sentence aloud. If the pause feels stronger than a comma but not quite a full stop, a semicolon might be the perfect fit.
