Epistrophe, also known as epiphora, is a rhetorical device that involves the repetition of a word or phrase at the end of consecutive clauses or sentences. There are various synonyms that can be used to describe this technique, such as antistrophe, epiphonema, and epilogism. Antistrophe highlights the contrast between different ideas by using repetition, while epiphonema is used to emphasize a particular point or conclusion within a discourse. Epilogism, on the other hand, is a more general term that can refer to any type of conclusion or summarization in speech or writing. Regardless of the specific term used, epistrophe can be a powerful tool for speakers and writers looking to create emphasis and impact in their communication.
