Morphology
prognathism = pro + gnath + ism
The word is built from the Greek combining elements pro- (forward) + gnath- (jaw) + the nominalizer -ism, a regular medical formation but using specialized combining forms unfamiliar to most B1 learners.
Etymology
Prognathism comes from Greek parts pro- 'forward' and gnath 'jaw'. So prognathism means a 'forward jaw', which is why it describes a jaw, often the lower one, that sticks out more than usual.
