Epistrophe (Greek: ἐπιστροφή, "return") is the repetition of the same word or words at the end of successive phrases, clauses or sentences.[1] It is also known as epiphora and occasionally as antistrophe. It is a figure of speech and the counterpart of anaphora. It is an extremely emphatic device because of the emphasis placed on the last word in a phrase or sentence.
Greek epistrophe: "a word coined by Plato as a goal of philosophical education and the term adopted by early Christians for conversion".[2]
— Shakespeare, The Tempest (4.1.108–109; 116–17)
In the beginning of this quotation by Barack Obama epistrophe is evoked, while the latter part makes use of anaphora.[3]
