Morphology

xeroderma + pigmentosum

This is a specialized Latinized medical diagnosis whose overall meaning (a genetic disorder causing extreme UV sensitivity and high skin-cancer risk) is not compositionally predictable from the parts. Even if a learner knew 'xeroderma' as dry skin and somehow parsed 'pigmentosum' as relating to pigment, they would not infer the specific pathological mechanism or cancer risk; the term is technical and language-specific rather than transparently descriptive to a B1 learner.

Etymology

Xeroderma pigmentosum comes from old Greek and Latin words: xero- meaning 'dry', derma meaning 'skin', and pigmentosum from 'pigment' meaning 'colour'. This picture of dry, changed skin after being in the sun helps you remember that the condition makes the skin very sensitive to sunlight and raises the chance of skin cancer.
