OAC

My Doubt: In OA how can a only a comma join the independent clause.

Please explain.

Thanks.

The sentence begins with "while," which is a subordinating conjunction.

If I write, Tim is in my class, I have never spoken to him. I have two independent clauses joined by a comma, and thus have a run-on sentence or comma splice. If, however, I start the sentence with a subordinating conjunction, such as "while" or "although" I'd have a valid construction. Although Tim is in my class, I have never spoken to him, is perfectly grammatical. "While" serves the same function in this question.
