Pronunciation

  • Ecclesiastical: [ˈɔb.lo.kʷor][1]

Forms

obloquor (present infinitive obloquī, perfect active oblocūtus sum); third conjugation, deponent[1]

Etymology

It is from Latin ob- + loquor (“to speak”),[2][3][1] literally “to speak against”.[4] loquor goes back to Proto-Italic *(t)lokʷ-e/o- and Proto-Indo-European *tlokʷ- (“to talk”).[5]

Earliest recorded meaning

It is first found in Plautus' Menaechmi, with the dative, of breaking in on a speaker: te morare mihi quom obloquere, “you hold me up when you interrupt me”.[2][6]

Semantic evolution

Plautus, Afranius and Cicero use it of interrupting and contradicting;[4][2] Cicero writes to his brother that he would like him to address him, interrupt him and talk with him.[4] Catullus uses it of railing at someone,[4] and in the Aeneid the singer obloquitur numeris septem discrimina vocum, accompanying the rhythm with the seven notes of the lyre;[2][4] Ovid uses it of birdsong.[4]

From Seneca on it means “to blame, find fault with”,[4] and the Vulgate has it in the Psalms.[4] In Ecclesiastical Latin it means to revile, slander or speak against.[7]
