Comma [,]:
What is the comma? A comma is a punctuation mark used to indicate separation that in spoken English is proved by a brief pause (or breathing space).

http://wiki.answers.com/Q/What_is_the_meaning_of_comma, September 11, 12

There are six rules for using commas.

1.       Use a comma before a coordinating conjunction (and, or, but, nor, yet, for, so) that separates two independent clauses. For example: One of our teachers gave us a lot of homework for next week, but he changes his mind and moves the due date.

2.       Use a comma after an introductory word, phrase, or clause that comes before a main clause. For example: Strangely, no one has suggested that Watergate gave us a "new Nixon."

3.       Use commas around words, phrases, and clauses in the middle of a sentence when they aren't essential to the meaning of the sentence. For example, this was not, in other words, an invisible 56 percent of the population.

4.       Use commas between items in a series. For example: Three reasons for the closing were insufficient enrollment, poor instructional materials, and inadequate funds.

5.       Use commas before and after a quotation within a sentence. For example: The band leader said, "Once the simple marching drill is learned, we will work on more maneuvers."

6.       Use a comma before an afterthought or contrasting element. For example: To understand a particular culture, we must consider the society as a whole, not its individual parts.
