Pronunciation

  • Classical: [nuː.ɡaːˈtoː.ri.ʊs][1]
  • Ecclesiastical: [nu.ɡaˈtɔː.ri.us][1]

Forms

nūgātōrius (feminine nūgātōria, neuter nūgātōrium); first/second-declension adjective[1] Old Latin has ⟨naugātōrius⟩.[2][3]

Etymology

It is from Latin nūgātor (“trifler, jester”) + -ius,[1][4][2] while the OLD analyses it as nūgor (“to trifle”) with the suffix ⟨-tōrius⟩.[5] Both go back to nūgae (“trifles, nonsense”), which de Vaan traces to Proto-Italic *knūg-.[6] He finds no Indo-European etymology; since words for trifles are sometimes made from words for nuts, a link with nux (“nut”) is quite likely, and the differences of vowel length and consonant suggest a foreign loanword.[6]

Earliest recorded meaning

De Vaan and Köbler date it from Plautus,[6][3] whose Trinummus has a man hired for three coins ad artis nugatorias, for tricks of storytelling.[5][7]

Semantic evolution

Its main sense is futile or absurd, of statements and arguments:[5][4] the Rhetorica ad Herennium calls one kind of argument futile, Cicero speaks of a bad and futile accusation, and a letter of Brutus and Cassius calls a point light and futile.[5] Varro uses it of a worthless ointment and of worthless Ligurian oxen.[5][4] Of persons it meant frivolous, not serious: Seneca reports that people call a man trifling and idle, and Ulpian speaks of a slave who wanders off and wastes his time on trifles.[5] It could also mean paltry, as when Seneca calls human bodies trifling and feeble.[5] The adverb nugatorie appears in the Rhetorica ad Herennium.[4]

Augustine uses it of opinions and songs and of a trifling kind of gods.[2][4] In British medieval Latin it meant trifling or superfluous, talking nonsense, untrue, and in logic meaningless.[8] English took it as nugatory about 1600.[9]
