Morphology

diarthrosis = arthrosis (opaque) = dia + arthr + osis

The prefix 'dia-' means 'through' or 'across', but the specific anatomical meaning of 'freely movable joint' is not directly derivable from the components.

Etymology

Diarthrosis comes from Greek parts: di- meaning 'through' or 'apart' and arthr- meaning 'joint', the same root you see in arthritis. So a diarthrosis is a joint where the bones are separated and can move freely, like the shoulder or knee.
