Adverb Clauses

Connecting ideas — and making your sentences do more work.

She studied hard because she wanted to pass the exam.

What Is an Adverb Clause?

No jargon — here's the simple version.

A group of words that gives extra information about when, where, why, how, or under what conditions something happens — and it always starts with a connector word.

💡 Think of it as a "why / when / how" add-on attached to your main sentence.

Without the clause

"She cried."

OK — but we don't know why.

With the clause

"She cried because she was happy."

✓ Now we know the reason!

Where Does the Clause Go?

The clause can come before OR after the main sentence — but the comma rule changes!

no comma

Pattern 1

Main Clause + Connector + Adverb Clause

She went home after the class ended.

comma ✓

Pattern 2

Connector + Adverb Clause , Main Clause

🔑 Key rule: When the adverb clause comes first, put a comma after it. When it comes last, no comma needed.
