A paraphrase /ˈpærəfreɪz/ is a restatement of the meaning of a text or passage using other words. The term itself is derived via Latin paraphrasis from Greek παράφρασις, meaning "additional manner of expression". The act of paraphrasing is also called "paraphrasis". A paraphrase typically explains or clarifies the text that is being paraphrased. For example, "The signal was red" might be paraphrased as "The train was not allowed to pass because the signal was red". A paraphrase is usually introduced with verbum dicendi—a declaratory expression to signal the transition to the paraphrase. For example, in "The signal was red, that is, the train was not allowed to proceed," the that is signals the paraphrase that follows.
