Pronunciation

  • Ecclesiastical: [iɱˈfaː.mo][1]

Forms

īnfāmō (present infinitive īnfāmāre, perfect active īnfāmāvī, supine īnfāmātum); first conjugation[1]

Etymology

It is from Latin īnfāmis (“disreputable”) + -ō.[2][1][3] That adjective is in- (“not”) with fāma (“reputation”).[3]

Earliest recorded meaning

The TLL finds it from Cicero, Nepos and Propertius on.[3] Cicero writes that a man's moderation and dignity bring the injustice of others into disrepute.[4]

Semantic evolution

It is to give a bad name to, bring into disrepute: Propertius says Jupiter disgraces himself and his house.[2][4] In law it is to disgrace with loss of rights, as the Digest says of a guardian who marries his ward.[2] It is also to attack someone's character, defame: Nepos says three weighty historians praised a man whom most had defamed.[2] The elder Seneca uses it of smearing with a particular suspicion.[2] Glosses explain it as accusing and speaking impiously.[3]

Timeline

  • 81–43 BC – Cicero.[4][3]
  • c. 100–24 BC – Nepos of defaming.[2]
  • 57/46–12 BC – Propertius of Jupiter's disgrace.[2]
