Parentheses

Remember that parentheses, though sometimes serviceable, are jarring to the reader. If you find them cropping up often in your writing, simplify your sentences or your thoughts; try including the parenthetical material some other way.

Punctuation: If the parenthetical material is a fragment and comes at the end of your sentence, place the period outside the parenthesis (as with this example). But if the parenthetical material stands alone as a sentence, include the period within the parenthesis: (Such are the basics of correct punctuation.)
