Morphology

allosaur = Allosaurus (semi-transparent) = allo + saur

Formed as a shortened/common-name from the genus Allosaurus; etymologically built from Greek combining forms ('allo-' + 'saur-') that are specialized and not obvious to average learners.

Etymology

The word allosaur comes from Greek parts allos meaning 'different' and sauros meaning 'lizard'. So allosaur is a 'different lizard', which helps you remember this large, meat-eating dinosaur that was not like the others.
