the.com/proteinuria

means A medical condition in which abnormal amounts of protein, especially albumin, show up in the urine, usually signaling that the kidneys' filtering units aren't working properly.

from A 19th-century medical coinage built from Greek pieces: 'proteios' (meaning 'primary' or 'first rank,' the root behind 'protein,' since protein was seen as a fundamental substance of life) plus 'ouron,' Greek for 'urine,' plus the medical suffix '-ia' denoting a condition. Doctors of the era were fond of stitching Greek anatomy words together to name whatever the body was doing wrong, and this one simply names the leak it describes: protein, in urine, as a diagnosable state.
