Learn how to use proper punctuation.

Below is a summary of how to punctuate different sentence patterns and how to analyze the likely effect of different syntactical forms on readers' comprehension.

Commas: Understand conventions for using commas and appreciate the likely effects of particular sentence lengths and patterns on reading comprehension.
Dashes: Create emphasis and define terms by interrupting the flow of a sentence using a dash; know when the dash must be used as opposed to the comma.
Colons: Use the colon when the first sentence anticipates the second sentence or phrase, thereby creating an emphatic tone.
Semicolons: Use a semicolon to join two sentences or to punctuate a series or list of appositives that already include commas.
