Etymology: Glomerulonephritis is a modern scientific coinage built from two parts that were each assembled from classical roots. "Glomerulo-" comes from "glomerulus," the Latin diminutive of "glomus," meaning a ball of thread or clew, a name that fits the tangled knot of tiny blood vessels inside each kidney filter. "Nephritis" comes from ancient Greek "nephros," meaning kidney, with the suffix "-itis" denoting inflammation. Put together, the word names inflammation of those glomeruli. The term is an internationalism, meaning it is built from the same classical building blocks across many languages, so physicians in different countries could recognise it at once. Ancient Greek and Roman physicians had no concept of the glomerulus as a distinct structure, so the word is a product of later anatomical study rather than of classical medicine. Its parts were put together from ready-made Latin and Greek pieces, which is how most precise medical vocabulary was made.

Synonyms: kidney inflammation, renal inflammation, glomerulitis, nephritis, glomerular disease
