Use a comma to separate an introductory word, phrase, or clause from the rest of the sentence. Example: Yes, I will go. After circling twice, the airplane landed. Although Tarzan needed help, he said nothing.
Commas with interrupters Use commas to set off words or groups of words that interrupt the flow of thought in a sentence. Example: Anne, to tell the truth, was quite happy. The reporter, moreover, is altogether inaccurate.
If you take out the interrupters, then the sentence will become complete. Example: The latest weather report, however, has predicted rain for the weekend. The latest weather report has predicted rain for the weekend.
