Morphology
retinitis + pigmentosa
The compound parts point to a retina-related condition ('retinitis') and pigmentation ('pigmentosa'), so a learner would likely infer it is an eye/retina disease. However the precise sense — a genetic, progressive degeneration causing vision loss rather than a straightforward inflammation — is technical and not fully predictable from the constituents (and 'pigmentosa' is a non‑transparent Latin/medical element for a B1 learner), making the relation only partially clear.
Etymology
Retinitis pigmentosa: The medical name retinitis pigmentosa comes from words doctors used to describe the eye. Retinitis points to the 'retina', the 'back of the eye', and pigmentosa refers to the dark pigment spots doctors saw there, so the name describes a disease where the retina slowly stops working and people lose sight.
