From the same root
Forms
obscēnitās f (genitive obscēnitātis); third declension[1] It is also spelled obscaenitās and obscoenitās.[2][3]
Etymology
It is from Latin obscēnus (“ill-omened; indecent”) + -tās.[2][4][1] De Vaan takes the spelling ⟨obscaenus⟩ as the original form of the adjective and finds worth considering its analysis as “coming from the left side”, from Proto-Italic *skai-no- (“left, unpropitious”), the root of scaevus (“left”).[5]
Earliest recorded meaning
The TLL records it from the Rhetorica ad Herennium on, which speaks of avoiding obscenity.[4][2] Cicero has turpissima obscēnitās verbōrum, “most shameful obscenity of words”.[2][4]
Semantic evolution
In Classical Latin it meant indecency of language, and then indecent behaviour.[2][3] Quintilian warns that obscenity must be absent not only from the words but from their meaning,[3] and Suetonius tells of a Roman knight accused of indecency towards women.[2][3] The TLL notes that among poets only Phaedrus uses it.[4]
Later writers took it concretely: Pliny the Elder has the plural for obscene figures on drinking cups, and Arnobius uses it for the genitals and for the inauspiciousness of a bad omen.[3] The English word obscenity came from it through French.[6]
