Surface Forms
Morphology
hypognathous = gnathous (opaque) = hypo + gnath + ous
The word is built from classical elements meaning 'under' and 'jaw,' but the specialized zoological sense is not readily inferable for average learners.
Etymology
Hypognathous comes from the parts hypo- 'under' and gnath- 'jaw', so picture a 'jaw under' the other. So, hypognathous describes animals whose lower jaw sticks out farther than the upper jaw.
