Morphology

chaetognath = chaet + gnath

Built from Greek combining forms ('chaet-' 'gnath-') that are not recognizable standalone words to an average B1 learner, so the meaning is not derivable from familiar English bases.

Etymology

Chaetognath comes from Greek parts chaeto- meaning 'bristle' and -gnath meaning 'jaw', so it literally means 'bristle-jaw'. This fits the animal: a clear sea worm with curved, bristle-like jaws at the sides of its mouth that it uses to catch prey.
