why is a comma necessary before words ending with “-ing”?
Question by maestro: why is a comma necessary before words ending with “-ing”?
examples:
1. “I dealt with him standing beside the door, looking at me and saying…”
2.”I started working the next day, cleaning the cages and helping the kids.”
3.”She is a former model, having modeled for a number of businesses and photographers”
@Cheyanne- you’re an idiot. You can’t put a semi colon because the second clause is an dependent clause, not independent. Semi colons are used to connect 2 independent clauses, when not using a fanboy between them.

It’s not the “-ing” that’s the reason for the comma. In each case, the comma sets off whatever phrase follows it.
The sentence:
“I dealt with him standing beside the door, all full of himself and saying…” would still require the comma even without the “-ing” wording.

If it were the case that a comma was required before an “-ing” word, the first two examples would need commas before the words “standing” and “working”.

An independent clause can stand alone, and is meaningful on its own. (He gave Sally the flowers)
A dependent clause has no meaning on its own It cannot stand alone. (Smiling like a nerd)
A comma is used to start a dependent clause, which uses the -ing verb.
Smiling like a nerd, he gave Sally the flowers. OR
He gave her the flowers, smiling like a nerd.
