Apostrophes
Step1
Use apostrophes with the letter "s" to show possession.
Step2
Use apostrophes to show that some letters in a word are missing.
Step3
Use apostrophes within dialogue to quote someone else. In American English, if the speaker quotes someone else, the part that the speaker is quoting should be surrounded by apostrophes, one on each end.
Step4
Use a single apostrophe next to a number to abbreviate feet.
Commas
Step1
Use commas when you list more than two things. Hot dogs, hamburgers and fried chicken are three types of food at a picnic. A comma goes between hot dogs and hamburgers because they are two separate things in the list.
Step2
Set apart phrases that do not affect the meaning of a sentence with commas. For example, I would put a comma after the words for example because you can get rid of these words without changing the meaning of this sentence.
Step3
Use commas around phrases that describe things in the middle of a sentence. For example, I have a brand new car, which is blue. Put a comma after the word car because the phrase which is blue is not necessary in the sentence. You can take that phrase out, and the sentence's meaning will not change.
Step4
Connect two complete sentences with a comma and a conjunction, such as and, but and or. Remember that a complete sentence needs a subject and a verb. If either the part before or after the conjunction is missing a subject or a verb, you do not need a comma.
Quotation Marks
Step1
Use quotation marks around titles of short works, such as poems and songs. Usually longer titles are underlined. Using different punctuation gives the reader clues about what the writer is referring to.
Step2
Put quotation marks around dialogue that someone has said, word-for-word.
Step3
Use one quotation mark next to a number to abbreviate inches.
Hyphens and Dashes
Step1
Use hyphens to connect related words that should be thought of as one unit. Black-and-white photograph is one example. A five-year-old child is another example. Here the phrases are joined by hyphens because all of the words together describe one thing, the photograph or the child.
Step2
Use an en-dash as bullets in a list. An en-dash is one length longer than a hyphen, but one length shorter than an em-dash.
Step3
Use an em-dash to set apart descriptive phrases in a sentence when there are too many commas.
Step4
Use an em-dash to set comments apart from the sentence. For example, an advertisement might say, "It cleans everything—even leather!" The phrase even leather is not necessary in the sentence. It actually works more like a comment to the reader than a part of the sentence. That is why it is set apart by an em-dash.

on 8/3/2007 You need to add that periods and commas go inside quotation marks. It's a common mistake to put them outside.
