Pronunciation
Forms
obscēnus (feminine obscēna, neuter obscēnum, superlative obscēnissimus); first/second-declension adjective[1]
Etymology
The origin is uncertain.[2][1] Lewis & Short and Georges derive it from ob and caenum “filth, mud”.[3][4] Pokorny, as Wiktionary reports, traces it to Proto-Indo-European *ḱweyn- (“to soil; mud”), with inquinō and caenum, though de Vaan calls a link between caenum and inquinō formally impossible.[1][5] Spellings obscaenus and opscēnus are found.[2][4]
Earliest recorded meaning
Plautus applies it to the private parts.[2] Köbler dates Plautus c. 250–184 BC.[6]
Semantic evolution
Its first sense in religion was ill-boding, ominous, as Lucilius' prayer that the king of the gods avert ill-omened words, Cicero, and Virgil's birds of ill omen.[2][7] It meant disgusting or filthy, as Virgil's Harpies and Ovid's foul laughter, and of the sexual and excretory parts and functions.[2][4]
Of language and conduct it meant indecent, obscene, as Cicero's “a most obscene story” and his discussion of whether anything is obscene to say.[2] As a noun it meant a foul-mouthed person or a pervert.[2] English obscene was borrowed from French in the 1590s.[8]
