Morphology

Pachycephalosaurus = pachy + cephalo + saurus

A scientific genus name made from Greek combining forms that are not standalone English words, so an average B1 learner cannot derive the meaning from common English base words.

Etymology

Pachycephalosaurus comes from Greek parts: pachy- 'thick', kephale 'head', and -saurus 'lizard'. So the name means 'thick-headed lizard', which helps you remember this dome-headed dinosaur with a very thick skull.
