Morphology

archosaurian + reptile

This is a compositional adjective+noun phrase where 'archosaurian' specifies a subgroup of 'reptile'; if a learner knows 'archosaurian' means 'of the Archosauria' and knows 'reptile', the overall meaning (a reptile belonging to that group) is directly derivable. Although the term is technical and domain-specific, its formation follows standard English modifier patterns and is therefore transparent to learners who know the constituents.

Etymology

Archosaurian reptile comes from old Greek parts archo- and -saurian, meaning 'ruler' and 'lizard'. So it gives the image of a 'ruler lizard' and is used for the extinct group of reptiles that included dinosaurs and other large ancient reptiles.
