Pronunciation

  • Classical: [ˈam.bɪ.ɡoː][1]
  • Ecclesiastical: [ˈam.bi.ɡo][1]

Forms

ambigō (present infinitive ambigere); third conjugation, no perfect or supine stems, third person-only in the passive[1]

Etymology

It is from Latin ambi- (“around”) + agō (“to drive, lead”).[2][3][1] De Vaan traces agō to Proto-Italic *ag-e/o- (“to do, act”) and Proto-Indo-European *h₂eǵ-e/o- (“to drive, lead”).[4] Cognate with Oscan acum (“to act (legally)”), Old Irish aigid (“drives”) and Ancient Greek ἄγω (ágō, “to drive, lead”).[4]

Earliest recorded meaning

The OLD's first example is in Terence's Heauton Timorumenos: “Simus and Crito are disputing here about boundaries”.[2]

Semantic evolution

It means to dispute or contend, and especially to be undecided, to doubt, as Velleius' “if anyone doubts this”.[2][5] Transitively it is to call into question or argue about, and in the passive to be in doubt; the impersonal passive ambigitur, there is a dispute, appears already in a law on an inscription.[2] Tacitus uses it once in its literal sense, of going round one's homeland and avoiding it.[5] It has no perfect: the TLL finds one only in grammarians.[5][3] Church Latin glosses it to doubt.[6]

Timeline

  • 190–159 BC – Terence of a boundary dispute.[2][7]
  • c. 20 BC–30 AD – Velleius of doubting.[2][7]
  • 98–115 AD – Tacitus of going around a place.[5][7]

Meanings

Verb

  1. To go about or around.[5][1]
  2. To dispute, quarrel, contend.[2]
  3. To be undecided or uncertain, to doubt, hesitate, waver.[2][5][1]
  4. Transitively, to call in question, argue about; in the passive, to be at issue; impersonally, there is a doubt or dispute.[2]
