Review of the Semicolon and Colon
 

  • Use a semicolon to separate two (or more) complete sentences whose ideas are related. Often the second sentence includes a pronoun that refers back to a noun (its antecedent) in the first sentence.

    The professor lectured on U.S. social policy; she then took questions.

  • My internship is with HRA; its mission is to serve the poor.

  • Use a semicolon in front of a transition word in a compound sentence. Remember to use a COMMA after the transition word. Transition words: for example, furthermore, however, in addition, nevertheless, on the other hand, therefore.

    Most of us were late to class; however, it didn’t matter as the professor was late as well.

    My area of study is administration; nevertheless, I'm only doing clinical work at my placement.

  • Use semicolons to separate a complicated series of phrases that contain commas.

    Grades will be based on class participation, assuming there will be time for discussion; two take-home exams, three in-class essays, and an occasional surprise quiz; and two presentations—one group and one individual.

  • Angel was in charge of publicity; Lisa, the programs; Carl, the props, lights, and food; and Dana, the sound system.

  • Use a colon after a complete thought to call attention to something that follows.

    I need one thing to make it through: brains.

  • Keep the following idea in mind: "All that is solid melts into air; all that is holy is profaned."

  • Use a colon before a list of items. These lists are often introduced by such words as: such as, as follows, the following, in the following manner.

    Please arrive with the following: two pencils, a writing pad, both textbooks, and your humor.
