Pronunciation

  • Classical: [sɪ.mʊˈɫaː.tɔr][1]
  • Ecclesiastical: [si.muˈlaː.tor][1]

Forms

simulātor m (genitive simulātōris); third declension[1]

Etymology

It is from Latin simulō (“to imitate, pretend”) + -tor,[2][1][3] an agent noun of the verb.[2] De Vaan derives simulō from similis (“like, similar”),[4] which goes back to Proto-Italic *semali- (“alike, together”) and Proto-Indo-European *smh₂-el-i-.[4]

Earliest recorded meaning

It appears in the 1st century BC in the sense “pretender”:[2] Sallust describes a bold, crafty mind as the simulator ac dissimulator of whatever it pleased, one who feigns and conceals,[2][5] and Cicero gives it as the Latin for Ancient Greek εἴρων (eírōn), one who feigns ignorance.[2][5]

Semantic evolution

Lewis and Short call the pretender the classical sense.[6] Tacitus has simulator segnitiae, a man who feigned idleness, and Ovid says that a lover who pretends often ends up loving in earnest.[2] The sense “imitator, copier” is poetic and rare:[6] Ovid calls Morpheus the craftsman and imitator of human shape,[2][6] and Claudian calls the ape an imitator of the human face.[6][5]

In medieval Latin it stayed the word for a feigner or trickster, and Alcuin glosses the Greek hypocrita as simulator in Latin.[7] Ecclesiastical Latin uses it for a hypocrite.[8] The Romance languages borrowed it: French simulateur, Italian simulatore, Spanish simulador.[1]

  • 86–34 BC – Sallust uses it of a mind that feigns and conceals at will.[2][3]
  • 81–43 BC – Cicero renders the Greek eírōn by it.[2][5][3]
  • 43 BC–18 AD – Ovid calls Morpheus an imitator of shape.[2][3]
  • 98–115 AD – Tacitus speaks of a man who feigned idleness.[2][3]
  • Medieval Latin – Alcuin equates it with the Greek hypocrita.[7]
