Epanalepsis, the repetition of a word or phrase at the beginning and end of a clause or sentence, is a rhetorical device with a long history. Single words exhibiting this characteristic, such as “rotor” or “level,” are called tautonyms. These structures appear in numerous contexts, from everyday language to specialized fields like linguistics and literature.
Such linguistic features contribute to mnemonic devices, making information easier to remember. They also add a sense of symmetry and closure, often heightening the impact of poetry, prose, and even advertising slogans. This elegant form of repetition dates back to ancient rhetoric and continues to play a role in persuasive and aesthetic language today, enhancing memorability and stylistic effect.
