Forms

labefaciō (present infinitive labefacere, perfect active labefēcī, supine labefactum); third (-iō variant) conjugation, suppletive[1]

Etymology

It is from Latin labō (“to totter, waver”) + faciō (“to make”), a compound meaning “to make totter”.[2][3][1] The passive is supplied by ⟨labefīō⟩, ⟨labefierī⟩.[2][4]

Earliest recorded meaning

It first appears in Terence, where a character complains that someone loosened all his teeth: omnīs dentīs labefēcit mihi.[2][5]

Semantic evolution

From making something physically unsteady, such as part of a wall,[4] the verb passed to figurative uses: to undermine power or authority and to weaken a person's resolve or loyalty.[2] L&S notes that Cicero uses only the participle labefactus.[4] The frequentative labefactō is derived from it.[1]

Ecclesiastical Latin uses it for “to shake, loosen, weaken”.[6]

Timeline

  • 190–159 BC – Terence uses it of loosened teeth.[2][5]
  • 81–43 BC – Cicero uses the participle of power and resolve that are shaken.[2][4][5]
