Morphology

cystinuria = cystine (semi-transparent) = cystine + uria

Formed from the biochemical noun 'cystine' plus the medical suffix '-uria' meaning a urine condition; the medical suffix is specialized and not obvious to general learners.

Etymology

Cystinuria comes from cystine, which is named after cyst meaning 'bladder' or 'small sac', and the ending -uria meaning 'urine'. So, cystinuria literally means 'cystine in the urine', which helps you remember that the condition is about too much cystine in the urine and can cause kidney stones.
