Morphology

supratrochlear + vein

The phrase is compositionally built from a locative anatomical descriptor ('supratrochlear' = above the trochlea) plus the concrete noun 'vein', so a learner who knows both parts can infer it denotes a vein in a specific anatomical location. However, 'supratrochlear' is a specialized medical term and the precise drainage function and connections in the full definition are domain-specific information not predictable from the parts alone, making the expression only partially transparent.

Etymology

Supratrochlear vein comes from the parts supra- meaning 'above' and trochlear meaning a small pulley-like part near the eye. The name makes a clear picture: the vein sits just above that part under the inner eyebrow, so it literally means 'the vein above the trochlea' and explains its current location.
