What Are Dashes and Parentheses

Dashes and parentheses are interruptions within the sentence that can provide extra information. In many cases, they may be necessary and valuable additions. Brackets are used only when inserting material into parentheses or around a word or phrase of your own that is added to a quotation.

Beginning writers sometimes overuse these punctuation marks. Generally, your writing should be direct and well organized, which means you will use dashes or parentheses sparingly.
