Plautus

Pronunciation

  • IPA (Classical): [ˈkas.sʊs][1]
  • IPA (Ecclesiastical): [ˈkas.sus][1]

Forms

cassus (feminine cassa, neuter cassum); first/second-declension adjective[1]

Etymology

The OLD tentatively takes it as a participle of careō “to lack”.[2][3] Wiktionary sees a verbal adjective from the root of careō and castus “pure”, perhaps from Proto-Indo-European *ḱes- (“to cut”), as Watkins also proposes.[1][4]

Earliest recorded meaning

Köbler's first source is Plautus, who has an empty nut and virgō dōte cassa “a girl without a dowry”.[3][5] Köbler dates Plautus c. 250–184 BC.[3]

Semantic evolution

It meant devoid of, lacking, as Lucretius' body deprived of light, and of seeds and stalks empty, hollow, as Plautus' nut and Ovid's barren reed.[2][5][6] It meant insubstantial, empty of meaning, of fears baseless, as in Lucretius, and fruitless, vain, as in Virgil, with in cassum “in vain”.[2] Lewis and Short call it mostly poetic.[6]

In Ecclesiastical Latin it meant useless, vain, empty.[7] A Late Latin verb cassāre “to annul”, from it, gave Old French casser and so one source of English quash “to make void”.[4]
