Clear Explanation

What Does a Comma Do?

A comma creates a short pause and helps organize sentences.

👉 Common uses:

1. In Lists

3. Between Clauses (with conjunctions)

• I was tired, so I went to bed.

What Does a Semicolon Do?

A semicolon creates a stronger pause than a comma but weaker than a period.

👉 Common uses:

1. Link Related Sentences

• I was tired; I went to bed.

👉 (Both parts could be full sentences)

2. Before Conjunctive Adverbs

• I was tired; however, I kept working.
• She studied hard; therefore, she passed.

3. In Complex Lists

• I visited Lahore, Pakistan; Delhi, India; and Dubai, UAE.

👉 (Used when items already contain commas)
