Comma Usage is a crucial writing skill for achieving clarity and coherence in IELTS and CELPIP writing tasks. This lesson demonstrates how to use commas effectively to enhance the readability and precision of your writing, ensuring your arguments are clearly understood.
Examples
Example 1
WeakWe bought apples oranges and bananas.
StrongWe bought apples, oranges, and bananas.

Example 2
WeakAfter the meeting we discussed the project.
StrongAfter the meeting, we discussed the project.
The strong sentence uses a comma after the introductory phrase for clarity.
How It Works
Meaning
Commas are punctuation marks used to indicate a pause between parts of a sentence. They help clarify meaning by separating elements within a sentence, such as items in a list, clauses, or adjectives. Proper comma usage is essential at the B2 level to enhance the readability and precision of your writing.
Use it when
- Listing multiple items or adjectives in a sentence.
- Separating independent clauses with a conjunction.
- Setting off introductory elements or phrases.
- Separating non-essential information or clauses within a sentence.

Quick rules

Common Mistakes
Common problem 1
missing a comma after an introductory clause or phrase
WeakAlthough the deadline was close the team finished on time.
StrongAlthough the deadline was close, the team finished on time.
Fix: Place a comma after any introductory clause (although, because, when, if…) before the main clause.
Common problem 2
using a comma instead of a semicolon to join two full sentences
WeakThe results were positive, the team decided to continue.
StrongThe results were positive; the team decided to continue.
Fix: Two independent clauses need a semicolon, a conjunction (and, but, so), or a full stop. not a comma alone.
Common problem 3
adding an unnecessary comma between the subject and its verb
WeakThe students who studied the hardest, passed the exam.
StrongThe students who studied the hardest passed the exam.
Fix: Do not put a comma between the subject and the main verb. even if the subject is long.
