lymphatic (adj.)youdaoicibaDictYouDict[lymphatic 词源字典]
1640s, from Latin lymphaticus, from lympha (see lymph). Also sometimes used in the classical Latin sense "mad, frenzied," which was the primary sense of lymphaticus in Latin: OED reports this "difficult to account for," but perhaps due to association of lympha with nymphe; compare Greek nymphian "to be frenzy-stricken."
