Pronunciation

  • Classical: [deːˈfae̯.koː][1]
  • Ecclesiastical: [deˈfɛː.ko][1]

Forms

dēfaecō (present infinitive dēfaecāre, perfect active dēfaecāvī, supine dēfaecātum); first conjugation[1]

Etymology

It is formed from Latin dē- + faex (“dregs”), with the verbal suffix ⟨-ō⟩.[2][3] Plautus also has the form dēficō.[2][4] Its past participle dēfaecātus is the source of English defecate.[5]

Earliest recorded meaning

Plautus has it first,[2][6] in the figurative sense of clearing or cheering the mind: animus defaecatus is an untroubled mood in the Aulularia.[7][6]

Semantic evolution

L&S call it ante-classical and post-Augustan.[4] Its literal use is for clearing wine of its dregs, in Columella and Pliny the Elder;[4][7][6] it also meant to wash or clean in general, and to purify or refine.[7] Christian writers used it of purifying the flesh from the stain of vices.[7] In Ecclesiastical Latin it meant to cleanse, refine or purify.[8]
