Morphology

choroid + coat

The compound is fully compositional: 'choroid' denotes a vascular layer in the eye and 'coat' denotes a thin covering or layer, so a learner who knows both constituents can infer it refers to a layer/coating (the choroid) of the eye. This follows standard anatomical noun + layer naming patterns, making the meaning predictable even though the term is technical.

Etymology

Choroid coat: The name comes from calling the dark middle layer of the eye a 'coat' that covers the inside; choroid is a word for a skin-like layer and coat shows it lies over the light-sensing part. So the picture of a dark 'coat' explains why it is the layer that brings blood and helps stop light from bouncing around inside the eye.
