In rhetoric, antimetabole (/æntɪməˈtæbəliː/ AN-ti-mə-TAB-ə-lee) 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.
[1] It is derived from the Greek ἀντιμεταβολή (antimetabolḗ), from ἀντί (antí, 'against, opposite') and μεταβολή (metabolḗ, 'turning about, change').
