Pronunciation

  • IPA (Ecclesiastical): [aɲˈɲɔs.ko][1]

Forms

agnōscō (present infinitive agnōscere, perfect active agnōvī, supine agnitum); third conjugation[1]

Etymology

It is from ad- (“to”) and nōscō “to get to know”, in its old form ⟨gnōscō⟩.[2][1][3]

Earliest recorded meaning

The OLD's first citations are from Plautus, of recognizing.[2] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

It meant to recognize, know again, identify, as in Plautus, to recognize someone's hand in a work, as Cicero's knowing God from his works, and to recognize as having some status, as in Cato.[2][5] It meant to acknowledge as one's own, a child, as in Nepos, or a deed, and in law to admit liability or accept an inheritance, as in Ulpian and Gaius.[2] It meant to recognize the value or truth of something, to accept an accusation, to acknowledge with gratitude, and to become aware of, realize, as in Cicero.[2] Pacuvius has the old participle agnōta.[2]

In Ecclesiastical Latin it meant to recognize, know, understand, perceive.[6] English agnostic, coined by Huxley in 1869, comes instead from Greek ágnōstos “unknown”.[7]
