Pronunciation

  • IPA (Classical): [prɔˈfɪ.te.ɔr][1]
  • IPA (Ecclesiastical): [proˈfiː.te.or][1]

Forms

profiteor (present infinitive profitērī, perfect active professus sum); second conjugation, deponent[1]

Etymology

It is from prō- “forth, publicly” and fateor “to acknowledge”, as Varro noted.[2][1][3] The Tabula Heracleensis has old forms ⟨profitērei⟩ and ⟨profitēminō⟩.[4]

Earliest recorded meaning

The OLD's earliest citation is from Ennius, of declaring openly.[2] Köbler dates Ennius 204–169 BC.[5]

Semantic evolution

It meant to declare openly, avow, as in Cicero, and to make a return of property to the authorities, and nōmen profitērī to enrol, as in Livy.[2][6] It meant to promise one's help, to undertake to be, and in Sallust indicium profitērī to volunteer evidence.[2] From Cicero it meant to profess, lay claim to a quality, to profess oneself to be, to make something one's profession, and to teach a subject publicly.[2] Döderlein explains that fatērī is to disclose, profitērī to avow freely and openly.[7]

In Ecclesiastical Latin it meant to profess, admit, acknowledge.[8] Its agent noun professor gave English professor in the late 14th century, and its participle professus gave English profess in the early 14th century, first “to take a vow”.[9]
