    While every word in a sentence should be carefully selected to create meaning for readers, not every word will be essential. Sometimes, you might interrupt your main idea with a word or phrase to add extra information; this non-essential word or phrase is called an “appositive.” Think about your everyday conversations with friends: you probably rarely get straight to your main point without pausing to add context or qualify a piece of information along the way. You can use this tactic in your writing to break up ideas for readers, emphasize key peripheral information, or incorporate a more conversational tone. To indicate to readers that you are pausing from the main idea, use commas around non-essential information to set it apart.
