"That Being Said..."

When there is a noun or a pronoun with a participle -- -ing or -ed form-- after it, it is called a nominative absolute. ...That being said, we will go forward from here. ...The project completed, we went out to celebrate. These take a comma wherever they are in a sentence. ...I will have to drop my argument, that being true. ...He had to have surgery, the leg being badly injured, on that same day. Happy punctuating!
