Punctuating Parenthetical Word Groups—Often writers will interrupt a sentence so they can add a comment. If these comments interrupt the flow of a sentence, or if the comments are not essential to the meaning of the sentence, they are considered parenthetical. Parenthetical comments, whether one word or a group of words, should be set off by punctuation. Four marks of punctuation can be used to identify parenthetical words or word groups: commas, dashes, parentheses, and brackets.
