Morphology

theropod = thero + pod

Formed from Greek combining forms meaning 'beast' + 'foot' (technical paleontological term); the components are not productive English morphemes familiar to average learners, so the meaning is not derivable by a typical B1 learner.

Etymology

Theropod comes from old Greek parts that mean 'beast' (thero-) and 'foot' (-pod), like tripod which also uses -pod for 'foot'. So a theropod is literally a 'beast-foot', a helpful image to remember these meat-eating dinosaurs had strong back feet and walked on them.
