Pronunciation

  • IPA (Classical): [ɪŋˈnoːs.koː][1]
  • IPA (Ecclesiastical): [iɲˈɲɔs.ko][1]

Forms

ignōscō (present infinitive ignōscere, perfect active ignōvī, supine ignōtum); third conjugation[1] Cato has the future participle ignōtūrus and Calpurnius Piso ignōscitūrus.[2]

Etymology

It is from in- and ⟨gnōscō⟩, the old form of nōscō “to get to know”.[2][1][3] Wiktionary takes the prefix as “after” and traces the sense from “to realise afterwards” to “acknowledge” and “forgive”.[1] The TLL reports Wackernagel's comparison with Sanskrit अनुज्ञा (anu-jñā, “to assent”).[3]

Earliest recorded meaning

The OLD's earliest citation is from Plautus, “to forgive”.[2] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

It meant to forgive someone an offence, with the accusative of the offence and the dative of the person, as in Plautus, and in a weaker sense to make allowances, indulge, as in Cicero.[2]

It survives in Italian ignoscere.[1]

Timeline

  • c. 250–184 BC – Plautus uses it.[2][4]
  • 81–43 BC – Cicero uses it of indulgence.[2][4]
