Pronunciation

  • Classical: [ˈra.bɪ.dʊs][1]
  • Ecclesiastical: [ˈraː.bi.dus][1]

Forms

rabidus (feminine rabida, neuter rabidum); first/second-declension adjective[1]

Etymology

It is from Latin rabiēs (“madness, rage”) + -idus, from the verb rabiō (“to rave”).[2][3][4] De Vaan finds the origin of ⟨rabiō⟩ uncertain: Schrijver compared Tocharian A rapurñe (“desire”), and the LIV an Iranian root seen in Parthian rf- (“to attack”), but both are isolated and doubtful.[4] Festus explained it from the dog's disease ⟨rabiēs⟩.[3]

Earliest recorded meaning

De Vaan dates it from Lucretius,[4] who has raging lions;[2] Köbler's first source is the Rhetorica ad Herennium.[5]

Semantic evolution

It is “raging, ravening”, of wild beasts, and of dogs in particular “rabid, mad”, as Seneca's sad sight of rabid dogs.[2][6] It is used of persons and monsters, as Ovid's raging Centaurs, of the Sibyl's frenzied mouth in Virgil, of raging waves, and of feelings: Catullus' Attis finds rest from the raging frenzy of his mind.[2] It is mostly poetic and post-Augustan.[6]

Church Latin glosses it “mad”.[7] English rabid (1610s) comes from it; its sense “infected with rabies” is from 1804.[8]
