Morphology

prognathous = prognathic (semi-transparent) = pro + gnath + ous

The formation is analyzable into the prefix 'pro-' (forward), the combining form 'gnath-' (jaw), and the adjectival suffix '-ous', but the Greek combining form 'gnath-' is not familiar to average learners so the meaning is not fully guessable.

Etymology

Prognathous comes from Greek parts pro- meaning 'forward' and gnathos meaning 'jaw'. So prognathous literally means 'jaw forward' and is used for a face where the lower jaw sticks out past the upper part of the face.
