Grammatical mistakes and examples

A common error when starting a sentence with because is creating a sentence fragment. A sentence fragment lacks an independent clause, which is a group of words that can stand alone as a sentence.


  • “Because I was late.”

This is a sentence fragment because it does not complete the thought – the consequence of being late is not expressed making the context incomplete.


  • “Because I was late, I missed the bus.”

Dependent and independent clauses

When starting a sentence with “because,” it’s crucial to understand the relationship between dependent and independent clauses.

  • A dependent clause, such as “because I was late,” cannot stand alone as a complete thought.
  • An independent clause, on the other hand, such as “I missed the bus,” can stand alone as a complete sentence.

In a sentence starting with “because,” the clause following because is usually a dependent clause and needs to be followed by an independent clause to form a complete sentence.


“Because I studied hard, I aced the test.”

  • Dependent clause: “Because I studied hard”
  • Independent clause: “I aced the test”


“Because she loves coffee, she decided to work in a café.”

  • Dependent clause: “Because she loves coffee”
  • Independent clause: “she decided to work in a café.”


You can, but it’s not recommended. Use this structure only when it enhances clarity or adds variety to your writing style.

Yes, it is formal as long as the sentence is grammatically correct and includes both a dependent clause and an independent clause.

Not necessarily. It only becomes a fragment if it lacks an independent clause.
