Morphology

archaeornis = archae + ornis

The name is a coinage from Greek combining forms ('archae-' + '-ornis') used in scientific nomenclature; these parts are not standalone English words and are not readily interpretable by an average B1 learner.

Etymology

Archaeornis comes from Greek parts archaeo- and -ornis, which mean 'ancient' and 'bird', and the first part is the same as in archaeology. So archaeornis is a name for an 'ancient bird', which fits because it was an early bird with teeth, a long feathered tail, and clawed wings.
