Pronunciation

  • Classical: [dɪf.faː.maːˈtoː.ri.ʊs][1]
  • Ecclesiastical: [dif.fa.maˈtɔː.ri.us][1]

Forms

diffāmātōrius (feminine diffāmātōria, neuter diffāmātōrium); first/second-declension adjective[1]

Etymology

It is formed from Latin diffāmātus + -tōrius,[1] from the stem of diffāmō (“to spread abroad, defame”).[2][3]

Earliest recorded meaning

It is first recorded in a charter of Lübeck of 1278, which speaks of a bishop and his clergy writing libellos diffamatorios, defamatory writings, against the friars and citizens.[4][2]

Semantic evolution

Throughout medieval and early modern Latin it kept the one sense of “slanderous, insulting”, said above all of words and writings: verba diffamatoria and libelli diffamatorii recur in charters from England to Hungary and Poland.[4][5][6][7] Ockham calls some decrees of Pope John “defamatory”.[5] Humanists such as Reuchlin still used it of a libellous book.[8] English took it over in the 1590s as defamatory, partly through French.[3]

Timeline

  • 1278 – A charter of Lübeck speaks of libelli diffamatorii.[4][2]
  • 1334 – Ockham uses it of papal constitutions he attacks.[5]
  • 1400 – A Polish court record speaks of mala verba diffamatoria.[7]
  • 1590s – English borrows it as defamatory.[3]
