Pronunciation

  • Classical: [ɪl.liː.bɛˈraː.lɪs][1]
  • Ecclesiastical: [il.li.beˈraː.lis][1]

Forms

illīberālis (neuter illīberāle); third-declension two-termination adjective[1] It is also spelled inlīberālis.[2][3]

Etymology

It is from Latin in- (“not”) + līberālis (“of a free man, generous”).[2][1][4] De Vaan lists līberālis among the derivatives of līber1 (“free”) (from Naevius on), which goes back to Proto-Italic *leuþ-ero- and Proto-Indo-European *h₁leudʰ-ero-.[5]

Earliest recorded meaning

Its first known use is in Terence's Adelphoe, where a character is shocked that so ignoble a deed (tam illīberāle facinus) should come from such a family.[2][4][6]

Semantic evolution

It describes what is unworthy of a free man:[2][3] the Rhetorica ad Herennium calls a kind of talk frivolous and illiberal,[4] and Cicero, in De officiis, counts as illiberal and sordid the earnings of hired labourers, whose labour, not their skill, is bought.[3][4] He also contrasts an illiberal, petulant kind of joking with an elegant one.[4] Pliny the Elder calls the radish a vulgar food.[4] Terence also uses it of a person lacking the qualities of a free man, and Gellius describes a girl whose face was not unrefined (haud illīberālī).[2][4]

A narrower sense is ungenerous or mean: Cicero writes that someone will think, not that his correspondent was mean towards him, but that he himself was careless,[2] and Livy speaks of an illiberal and ungrateful mind.[4]
