Syntax & Structure

Chiasmus

Chiasmus involves the repetition of words or grammatical structures in reverse order to create a parallel and balanced phrase or sentence. This device creates a symmetrical and memorable effect in the language, often used for emphasis or to add a poetic or rhetorical quality to the writing. Chiasmus can involve a range of linguistic elements, such as words, phrases, clauses, or even entire sentences.

Chiasmus arranges corresponding elements in a crossed order, commonly ABBA. Identify what occupies A and B, then show how the reversal reshapes emphasis or relationship.

She shaped the story, and the story shaped her.
Subject and object roles reverse in an ABBA pattern.
