* If "regarding" is introducing a dependent clause, you usually need a comma:
* "I have some questions regarding your recent order, please contact me at this number."
* If "regarding" is introducing a prepositional phrase, you usually don't need a comma:
* "I have some questions regarding the upcoming event."
Here's a simple way to think about it:
* Comma: If the sentence can stand alone without the phrase after "regarding", you likely need a comma.
* No comma: If the phrase after "regarding" is essential to understanding the sentence, you likely don't need a comma.
Example:
* "I have some questions, regarding your recent order." (Comma needed - "I have some questions" is a complete thought)
* "I have some questions regarding your recent order." (No comma needed - "regarding your recent order" is essential to understanding the questions)
