Antanaclasis
In rhetoric, antanaclasis (; from the Greek: ἀντανάκλασις, antanáklasis, meaning "reflection", from ἀντί anti, "against", ἀνά ana, "up" and κλάσις klásis "breaking") is the literary trope in which a single word or phrase is repeated, but in two different senses. Antanaclasis is a common type of pun, and like other kinds of pun, it is often found in slogans.
