Commas are the most frequently used (and abused) punctuation mark in most kinds of writing. The reason for this is that they have so many uses and so many rules—it can be hard to keep track of them all. A colon is used to make lists and tell the reader, “This is what I mean.” The colon should not be used often in most kinds of writing unless there are extensive lists involved. The rules of the colon are strict but fairly easy to remember. semicolon is used to separate two ideas (two independent clauses) that are closely related. They can also be used when listing complex ideas or phrases that use commas within them. Essentially, a semicolon is like a comma with more meaning or a colon with more flexibility.The dash (or, more specifically, the “em dash”) is perhaps the most versatile of the punctuation marks. However, like the semicolon, it is underutilized in most kinds of writing. It can function like a comma, parentheses, or colon, but creating subtly different effects in each case.
