Morphology
hadrosaur = dinosaur (semi-transparent) = hadro + saur
The parts signal a reptilian, dinosaur-like creature (learners familiar with 'dinosaur' or the combining form '-saur' can infer it's a dinosaur), but the precise meaning 'duck-billed hadrosaur' is not deducible from the components alone.
Etymology
Hadrosaur comes from Greek parts hadro- meaning 'thick' or 'large' and -saur meaning 'lizard', the same -saur you see in dinosaur. So a hadrosaur is literally a 'large lizard', which fits these big, mostly plant-eating dinosaurs with a duck-like bill.
