Document Summary
The comma is punctuation that separates, joins, sets off, or introduces specific parts of a sentence. Let"s take a look at the most important uses of the comma. Commas are used to separate three or more grammatically similar items in a series or list. Ryan usually walk, swim, or bike before breakfast. A comma comes after each item in the series, except the last one. The last item has a coordinating conjunction before it. Items in a series might be single words or longer word groups. The sharply hit ball went over the pitcher"s head, under the shortstop"s glove, and through a centerfield gap. Commas separate the prepositional phrases and the coordinating conjunction and comes just before the last phrase. A coordinating conjunction usually comes before the last item in a list. You can remember the seven coordinating conjunctions with the acronym fanboys. A comma is also used with a coordinating conjunction to join independent clauses.
