Pronunciation

  • Classical: [ĩːˈsɪ.mʊ.ɫoː][1]
  • Ecclesiastical: [inˈsiː.mu.lo][1]

Forms

īnsimulō (present infinitive īnsimulāre, perfect active īnsimulāvī, supine īnsimulātum); first conjugation[1]

Etymology

It is from Latin in- + simulō (“to imitate, pretend”).[2][1] The verb simulō is made from similis (“like”),[1] which de Vaan traces to Proto-Italic *semali- (“alike, together”) and Proto-Indo-European *sm̥h₂-el-i-.[3] Cognate with Ancient Greek ὁμαλός (homalós, “equal, level”).[3]

Earliest recorded meaning

De Vaan dates it from Plautus,[3] who has “you do wrong to accuse an innocent woman”.[2]

Semantic evolution

It means to accuse, charge or blame, and to put forward as a charge, as Plautus' “that crime you charge us with does not befit our family”.[2] Lewis & Short describe it as making a plausible charge, true or false, against someone, especially falsely.[4]

Timeline

Usage notes

Döderlein says that insimulāre is to accuse undeservedly or slanderously, out of suspicion, as against arguere, the general word, and accūsāre, to impeach in a criminal court.[6]
