Morphology
peristaltic = peristalsis (transparent) = peristalsis + tic
Formed from the noun 'peristalsis' with the regular adjectival suffix '-tic' meaning 'relating to', so the relationship is directly derivational.
Etymology
The word peristaltic comes from Greek parts peri- meaning 'around' and -staltic meaning 'to squeeze or send along'. So a peristaltic movement is like a ring of muscle that squeezes a tube in a wave, pushing food or liquid forward.
