enarthrosis = arthrosis (opaque) = en + arthrosis

Formed from Greek medical elements and denotes a specialized anatomical type of joint; the meaning is unlikely to be inferable by an average B1 learner from the parts.

Etymology

Enarthrosis comes from Greek parts en- 'in' and arthron 'joint'. So an enarthrosis is a joint where the rounded head of one bone fits into the cup-like part of another, like a ball in a socket, which is why it can move in many directions.
