Schematismos
Schematismos is a term used in rhetoric and literary criticism to describe a figure of speech that involves a deviation from the ordinary or expected way of expressing an idea for the sake of emphasis or beauty. It is a broad category encompassing a variety of stylistic devices that alter the typical structure or arrangement of words. These alterations can involve changes in sentence structure, word order, or the repetition and omission of words.
Common examples of schematismos include chiasmus, where a phrase is repeated in reverse order, and anaphora,
