A subordinate clause always begins with a subordinating conjunction – also known as a subordinate clause word. Here are some common subordinating conjunctions: if, when, before, after, because
When you begin a sentence with one of these words, you are writing a subordinate clause. A subordinate clause cannot stand alone – it must be attached to an independent clause. Look at these examples:
If it rains, our game will be postponed.
When the bell rings, recess begins.
Before we eat dinner, we have to buy groceries.
After I practice piano, I’ll take a walk with you.
Because I need money, I am working at the bowling alley.
Each sentence begins with one of the subordinate clause words, and each subordinate clause is followed by a comma and an independent clause.
Whenever you begin a sentence with the subordinate clause words if, when, before, after, because,
you are writing a subordinate clause. You need to follow the subordinate clause with a comma and an independent clause to make a complete sentence.
It’s your turn. Write a subordinate clause beginning with the subordinating conjunction if. Then use a comma and an independent clause to finish your complete sentence. Did you figure it out? Good for you!
