Figure of Speech: anadiplosis (an-a-di-PLO-sis), the last-word, first-word repetition.
Generals don’t like Rummy. Congress doesn’t like him either. He fails to defer to generals and members of Congress. Oh, and he screwed up the war in Iraq.
But Bush is the decider, and he uses an anadiplosis ("redouble") to announce his decidingness. The figure takes the last word of a phrase and repeats it in the beginning of the next phrase, giving an overlapping effect to a sentence — sort of like roof tiles, making the whole thing logically watertight.
An anadiplosis can also make you sound like a hip hop artist; in this case, a very white hip hop artist. You got to work on that rhythm, Dawg.
