Was My Teacher Right or Wrong?

In third grade, Mrs. Andersen taught me that I should never start a sentence with the word because. Is that correct, or was dear Mrs. Andersen wrong?

Dependent Clauses & Independent Clauses

First, we need a refresher on clauses. Clauses are groups of words that contain a subject and a verb. There are two types: dependent clauses and independent clauses.

Dependent clauses don't express complete thoughts. If they're used all by themselves, they are only sentence fragments.

after the sun went down

because I was thirsty

Independent clauses express complete thoughts.

The party started.

I drank three bottles of water.

Dependent clauses need to be connected to independent clauses in order to form complete sentences.

After the sun went down, the party started.

I drank three bottles of water because I was thirsty.

Can You Start A Sentence With Because?

Because is a subordinating conjunction. Subordinating conjunctions introduce dependent clauses. They also join the dependent clause to the independent clause.

Contrary to Mrs. Andersen's instruction, it can be okay to start sentences with because. When you do, you're starting a sentence with a dependent clause. Just make sure that your dependent clause is followed by a comma and an independent clause or you'll most likely end up with a fragment rather than a complete sentence.

Because I was thirsty, I drank three bottles of water.

Because it was cold, I wore my warm coat.

What Should She Have Done?

If Mrs. Andersen would have let us start sentences with because, students probably would have been handing in papers with sentence fragments, and she would have become very frustrated.

In order to teach the class how to correctly start sentences with because, she would have had to teach us about subordinating conjunctions, dependent clauses, and independent clauses.

If students are already familiar with clauses, conjunctions, and other grammar topics, it's much easier to teach them nuanced writing rules like this. If they're not, it can be almost impossible.

It's understandable that Mrs. Andersen didn't want us to start sentences with because since we didn't know enough about grammar to do it properly.

However, instead of teaching us that it was never okay, perhaps Mrs. Andersen could have told us that starting sentences with because is something that we'd learn to do later, after we knew more about grammar.

And then, of course, we should have had grammar lessons that taught us these concepts and more!
