Epanalepsis

The epanalepsis is a figure of speech defined by the repetition of the initial word (or words) of a clause or sentence at the end of that same clause or sentence. The beginning and the end are the two positions of stronger emphasis in a sentence; so, by having the same phrase in both places, the speaker calls special attention to it. Nested double-epanalepses form another figure of speech, which is called an antimetabole.
