Can you start a sentence with "because"? Certainly!

"Because" is a subordinating conjunction; it introduces a subordinate clause. And there is nothing wrong with starting a sentence with a subordinate clause—as long as the sentence also includes a main clause.



Because I was tired.

Because I was tired, I took a nap.

Because I was hungry.

Because I was hungry, I ate lunch.

Because I love her.

Because I love her, I let her go.


Remember: Subordinate clauses cannot live alone; they always need a main clause in order to survive.



While you were out.

  • While you were out, someone called.
  • Someone called while you were out.

After I got home.

  • After I got home, I did my homework.
  • I did my homework after I got home.

If it rains.

  • If it rains, I will stay inside.
  • I will stay inside if it rains.


Why did my elementary school teacher tell me that I cannot start a sentence with "because"?

She was trying to keep it simple. A more complete answer might have sounded something like this:

"Yes, you can start a sentence with 'because', but remember that a sentence that starts with 'because' is always part of a 2-part sentence. If you start a sentence with 'because', you must also include the 2nd part of the sentence."

In the second example, the connection between the answer and the question is implied or understood.
