Morphology

spider + nevus

The compound combines 'spider' (indicating a spider-like radiating shape) with 'nevus' (a skin blemish), so the idea of a skin lesion with radiating capillaries is directly inferable from the constituents. This shape-based naming is common in medical vocabulary and across languages, making the MWE readily understandable to a learner who knows both words.

Etymology

Spider nevus gets its name from how it looks: a small red spot with thin lines spreading out like a spider's legs, and nevus is a medical word for a skin spot. So, doctors use the name to mean 'a small, spider-shaped blood vessel on the skin'.
