Antimetabole

In rhetoric, antimetabole ( ) is the repetition of words in successive clauses, but in transposed order; for example, "I know what I like, and I like what I know". It is related to, and sometimes considered a special case of, chiasmus.
An antimetabole can be predictive, because it is easy to reverse the terms. It may trigger deeper reflection than merely stating one half of the line.
Etymology.
It is derived from the Greek (), from (, "against, opposite") and (, "turning about, change").
