Word History

Etymology

borrowed from New Latin, genus name, going back to Latin alysson "a kind of madder," borrowed from Greek álysson "any of several plants used to treat rabies," noun derivative from neuter of ályssos "curing madness," from a- a- entry 2 + -lyssos, adjective derivative of lýssa, Attic lýtta "rage, frenzy, rabies," perhaps derivative, with the abstract noun suffix *-ya (going back to Indo-European *-i̯h₂) from the stem of lýkos "wolf" — more at wolf entry 1

Note: An alternative hypothesis sees a connection with Indo-European *luk-, zero grade of the base *leu̯k- "light, bright" (see light entry 1), assuming an association between rage or frenzy and unnaturally sparkling eyes. Support for this association is allegedly given by the phrase in Pindar leukaîs pithḗsanta phrasín "heeding his bright/flashing/violent (?) heart," along with Hesychius's gloss of leukaî phrénes as "raging" (mainómenai).
