c.1300, from O.Fr. jaunisse "yellowness" (12c.), from jaune "yellow," from L. galbinus "greenish yellow," probably from PIE *ghel- "yellow, green" (see Chloe). With intrusive -d- (cf. gender, astound, thunder). Meaning "feeling in which views are colored or distorted" first recorded 1629, from yellow's association with bitterness and envy (see yellow).
