Epizeuxis
In rhetoric, epizeuxis is the repetition of a word or phrase in immediate succession, typically within the same sentence, for vehemence or emphasis. A closely related rhetorical device is diacope, which involves word repetition that is broken up by a single intervening word, or a small number of intervening words. As a rhetorical device, epizeuxis is utilized to create an emotional appeal, thereby inspiring and motivating the audience. However, epizeuxis can also be used for comic effect.
