Here you can find one very common punctuation mistake of using because in English language :
| Correct | Incorrect |
|---|---|
| She didn’t come to work today. Because she doesn’t feel good. | She didn’t come to work today because she doesn’t feel good. |
Reason why is this using of because is wrong is this – because is a subordinating conjunction.
By english grammar rules subordinating conjunction can’t be separated by a full stop from its main clause.
