🔗 Understanding Clauses

A clause is a group of words that contains both a subject and a verb.

Independent Clauses

Can stand alone as a complete sentence (has a subject and verb, and expresses a complete thought)

The sun is shining.

I love reading books.

These are complete sentences by themselves!

Dependent Clauses (Subordinate Clauses)

Cannot stand alone as a complete sentence (has a subject and verb, but does NOT express a complete thought)

Because it was raining (incomplete - what happened?)

When I finish my homework (incomplete - then what?)

If you study hard (incomplete - what will happen?)

These need to be connected to an independent clause!

🏗️ Building Complete Sentences

Dependent clauses must be attached to independent clauses to form complete sentences.

Dependent + Independent

Because it was raining, we stayed inside.

When I finish my homework, I can play video games.

If you study hard, you will pass the test.

Independent + Dependent
