uric (adj.)

c. 1300, from Old French orine, urine (12c.) and directly from Latin urina "urine," from PIE *ur- (source also of Greek ouron "urine"), variant of root *we-r- "water, liquid, milk" (source also of Sanskrit var "water," Avestan var "rain," Lithuanian jūrės "sea," Old English wær, Old Norse ver "sea," Old Norse ur "drizzling rain"), related to *eue-dh-r (see udder).

1928 (morphine barbiturate is from 1918), with chemical ending -ate (3) + barbituric (1865), from German barbitur in Barbitursäure "barbituric acid," coined 1863 by chemist Adolf von Baeyer. The reason for the name is unknown; some suggest it is from the woman's name Barbara, others that it is perhaps from Latin barbata, in Medieval Latin usnea barbata, literally "bearded moss." The second element is because it was obtained from uric acid. Related: Barbitol.
