'nonperistaltic' originates from Modern English, specifically the prefix 'non-' and the adjective 'peristaltic', where 'non-' meant 'not' and 'peristaltic' ultimately derives from Greek 'peristellein' (to roll around) via New Latin/Modern formation.

'peristaltic' comes from Greek 'peristaltikos' (from 'peristellein'), passed into scientific New Latin and then into Modern English as 'peristaltic'; the negative form 'nonperistaltic' was formed in Modern English by adding the productive prefix 'non-' to this adjective.

Initially, the root referred to the action 'to roll around' (Greek); over time it came to name the physiological wave-like muscular contractions ('peristalsis'), and 'nonperistaltic' developed to describe the absence of that action.
