An antimetabole is a rhetorical device accentuated by the reversal of words, actions, or grammatical structure.

An example of an antimetabole in "Cry, the Beloved Country" is the line "Cry, the beloved country, for the unborn child that is the inheritor of our fear" where the words "Cry" and "beloved country" are repeated in reverse order. This rhetorical device is used to emphasize the sorrow and concern for future generations in South Africa.

It's a figure of speech where the second half of the clause is repeated or restated similarly in reverse.

Ex: I want what I like and I like what I want.

Personification: "Time's fell hand", "buried age", "hungry ocean", "ruin hath taught me."

Antimetabole: "Increasing store with loss and loss with store."

Metaphor: "The kingdom of the shore"
