the.com/glomerulonephritis

means A disease in which the kidneys' tiny filtering units (the glomeruli) become inflamed, often through immune-system misfiring, impairing their ability to filter blood properly.

from Built from three borrowed pieces: 'glomerulus' is Latin for 'little ball' (a diminutive of glomus, 'ball of thread'), fittingly describing the tiny tangled clusters of blood vessels that do the filtering; 'nephros' is Greek for 'kidney'; and '-itis' is the Greek suffix doctors use to flag inflammation. String them together and you get a precise anatomical diagnosis disguised as a tongue-twister: inflammation of the kidney's little filtering balls.
