Etymology: Oliguria is a medical coinage built from parts that are each old, but the combination is modern. Its first half comes from Ancient Greek "olígoi," meaning "few," which gives the prefix "olig-" as in "oligarchy" (rule by few). The second half, "-uria," is a suffix from the Greek "oûron," meaning "urine," seen in many diagnostic terms for urine conditions, such as "polyuria" (excessive urination) and "glycosuria" (sugar in the urine). The pattern is deliberate: a physician describing a patient who passes only small amounts of urine could combine these Greek pieces into a precise clinical label. Ancient Greeks and Romans did not use the word itself, since the Greek and Latin roots were assembled into a new technical term rather than inherited from classical writers.
