Pronunciation

  • Classical: [ɔp.stʊ.pɛˈfa.ki.oː][1]
  • Ecclesiastical: [ob.stu.peˈfaː.t͡ʃi.o][1]

Forms

obstupefaciō (present infinitive obstupefacere, perfect active obstupefēcī, supine obstupefactum); third (-iō variant) conjugation, suppletive[1] The passive is obstupefīō, obstupefierī.[2][3] Terence scans it obstupēfecit.[2][4]

Etymology

It is from Latin ob- + stupefaciō (“to stun, stupefy”).[2][4] That verb is formed from stupeō (“to be stunned”) and faciō (“to make”).[1] De Vaan traces the base to Proto-Italic *stup-ē- (“to be stunned”) and Proto-Indo-European *stup-eh₁- (“to hit, push”), a meaning that explains the stative sense of the verb; he compares Ancient Greek τύπτω (túptō, “to hit, strike”).[5]

Earliest recorded meaning

Its first use is in Terence's Phormio, of a man who could not utter what he had planned: ita eum tum timidum ibi obstupefecit pudor, “so did shame strike him dumb, timid as he was”.[2][6][7]

Semantic evolution

It means to strike someone dumb with a strong emotion, to stun or astound: Cicero uses it of people stunned by admiration, Livy of an enemy stunned by the sheer daring of a deed,[2][6] and of fear paralysing grief.[2][3] Cicero also uses it of the part of the soul dulled by too much food and drink,[2] and Valerius Maximus of nerves and limbs numbed by cold.[2][8] In Ecclesiastical Latin it means “to astonish, amaze”.[9] One manuscript of Jerome's translation of Job spells it obstubef-.[4]
