Pronunciation

  • Classical: [ˈskiː.tɔr][1]
  • Ecclesiastical: [ˈʃiː.tor][1]

Forms

scītor (present infinitive scītārī or scītārier, perfect active scītātus sum); first conjugation, deponent[1] Ovid uses the old infinitive ⟨scītārier⟩.[2][3]

Etymology

It is from Latin scīscō (“to seek to know”) + -tō, built on the stem ⟨scīt-⟩ of its participle.[4][1] Lewis and Short derive it directly from sciō (“to know”), and de Vaan lists it among the derivatives of that verb, from Plautus on.[2][5] He takes the verb to be probably a back-formation from nesciō (“not to know”); it goes back to Proto-Italic *skije/o- (“to know”), and perhaps to a root meaning “cut off, incise”, Proto-Indo-European *skh₁-i(e/o)-.[5]

Earliest recorded meaning

De Vaan dates it from Plautus,[5] whose Captivi has sunt quae ex te solo scitari volo, “there are things I want to learn from you alone”.[2][6]

Semantic evolution

It means to seek to know, to inquire about something, often with ex or ab for the person asked.[4][3] Lewis and Short call it poetic and late: in Cicero's Orator editors now read sciscitari instead.[2][3] Virgil has scitari et quaerere causas, to inquire and seek the causes, and uses it of sending Eurypylus to consult the oracle of Phoebus;[2][4] Horace has it with ex, and Ovid uses it often, of asking the cause of a journey or of a coming.[2][6] With a person as object it means to question.[4]

Ammianus Marcellinus uses it of consulting the decrees of the gods and of finding out what an enemy was planning.[2][3]

Timeline

  • c. 250–184 BC – Plautus uses it of wanting to learn something from one person.[2][6][7]
  • 70–19 BC – Virgil uses it of consulting an oracle.[4][2][7]
  • 43 BC–18 AD – Ovid uses it often, once with the old infinitive ⟨scītārier⟩.[2][7]
  • c. 390 AD – Ammianus Marcellinus uses it of finding out an enemy's plans.[2][3][7]

Usage notes

A separate noun scītor, scītōris, “one who knows, an expert”, formed from sciō, is found in Claudianus Mamertus.[3][8][7] A British glossary uses it for one who inquires.[9]
