Punctuation marks: How to use the COMMA
Using the the comma ( , ) is the most difficult of all the punctuation marks. Usage varies greatly in different types of writing. Equally good writers and proofreaders also question the use of the comma in certain passages of writing. The English language has certain general rules governing the proper use of the comma. Many cases, however, will arise in which you will interpret the rules differently or use the comma differently based on style guides like APA Style and MLA Style.
The comma is the least degree of separation. Its business is to define the particles and minor clauses of a sentence. When we look back to the last century and fast forward to present day, we can see that writers favor the semicolon more than the comma in wordy sentences. Today's writers favor simplicity of expression. They write clear and simple English. They have completely abandoned the old style of ornate writing which involved a good deal of punctuation to make it intelligible. A simple and direct writing style needs very little help--and little punctuation.
The change in writing styles over the last century and the attitude of writers wanting to simplify writing account for the difference in usage of the comma and difficulty in fixing rules to cover all cases. The present attitude toward punctuation, especially the use of the comma, is one of dislike. The writer is always accountable to explain the presence of a comma rather than its absence. Nevertheless, it is possible to go too far in removing commas in ordinary writing. It is possible to create sentences in such a way as to avoid the comma. The result is a harsh and awkward style, unwarranted by any necessity. Ordinary writing needs the companionship of commas to indicate the sense and to prevent ambiguity.
Always remember that the primary use of the comma is to help bring forth the meaning of the words and prevent ambiguity. A correct use of the comma shows clearly the separation and connection of words and phrases. If you think your readers might misunderstand your sentence without a comma, then put one in. If the words tell their story clearly, without misunderstanding, then leave it out. This rule is dependable in the absence of any recognized rule for a particular case, or where doubt exists as to the application of a rule.
1) Use a comma after each adjective or adverb in a series of two or more when not connected by conjunctions.
EX. He was a tall, thin, dark man.

1) The comma is used to separate for the eye what is separate in thought.
2) The comma is not intended to break the content up into lengths suited to the breath of one reading aloud.
3) The comma is not an aesthetic device to improve the appearance of the line.
4) The sole purpose of the comma is to unfold the sense of the words.
5) The comma cannot be correctly used without a thorough understanding of the sense of the words.
6) When in doubt, leave it out.
