When we paraphrase, we provide a version that can exist beside the original (rather than replace it). We paraphrase all the time. When you tell a friend what someone else has said, you're almost always paraphrasing, since you're not repeating the exact words. If you go to hear a talk, you might paraphrase the speaker's main points afterward for your friends. And when writing a paper on a short story, you might start off your essay with a paraphrase of the plot. Paraphrasing is especially useful when dealing with poetry, since poetic language is often difficult and poems may have meanings that are hard to pin down.
