Phrases within parentheses often give further detail about the concepts being presented, such as: "The store was nearby (just two houses down)." Place a phrase that would otherwise qualify as a sentence -- but depends on the surrounding information for context -- within the parentheses, and insert the end punctuation after the final parenthesis, as follows: "The store was nearby (it was just two houses down)." If the parenthetical section is a full sentence, capitalize the first word of the sentence and use end punctuation within the parentheses, for example: "The store was nearby. (It was just two houses down.)"
Documentation Formats and Parentheses
In Modern Language Association format, if you use information from a source, include the last name of the author of the source along with a page number where you found the information, as follows: (Smith 3). For American Psychological Association style, include the author's last name and the date that the article was published in parentheses along with a page or paragraph number for direct quotes, as follows: (Smith, 2014, p. 2). Note that when you paraphrase information in APA style, place the sentence's end punctuation immediately after the closing parenthesis. For direct quotes, insert quotation marks before the parentheses, for example: "Writers often use such techniques" (Jefferson, 2014, para. 3).
