Origin: A borrowing from German, combined with an English element. Etymons: German Myoctoninsäure , -ic suffix.
Etymology: < Myocton- (in German Myoctoninsäure (T. Peckolt 1866, in Arch. der Pharm. 177 96); < ancient Greek μυοκτόνος mouse-killing < μυο- (see myo- comb. form) + -κτόνος slaying < κτείνειν to kill, probably cognate with Sanskrit kṣan- to hurt, injure) + -ic suffix. Compare Hellenistic Greek μυοκτόνος, classical Latin myoctonon (Pliny) mouse-killing plant, aconite.For a similar formation directly < Greek compare earlier tyrannoctonic adj. at tyranno- comb. form . In his 1866 paper (see above) Peckolt gives Spanish herva de rato rat herb (German Rattenkraut) as the vernacular name of Palicourea marcgravii, the source of myoctonic acid. N.E.D. (1908) gives the pronunciation as (məiˌoktǫ·nik) /maɪəʊˈktɒnɪk/.
