Morphology

fenestra + rotunda

The composition is literally noun + adjective: 'fenestra' = opening and 'rotunda' (Latin/derived) = round, so a learner who knows both constituents can infer it denotes a round opening. However, the specific anatomical sense ('the round window in the middle ear leading to the cochlea') is technical and not fully predictable from the parts alone, so the transparency is only partial.

Etymology

Fenestra rotunda comes from Latin words fenestra ('window') and rotunda ('round'), giving the clear image of a small round 'window' in the wall of the middle ear. That's why the term now means a small round opening that leads into the cochlea, the spiral part of the inner ear that helps us hear sound.
