Pronunciation

  • 5th-century BC Attic: /ɡnɔ̂ː.sis/[1]
  • 4th-century AD Koine: /ˈɣno.sis/[1]
  • 10th-century Byzantine: /ˈɣno.sis/[1]

Forms

γνῶσῐς (gnôsis) f (genitive γνώσεως); third declension[1]

Etymology

It is inherited from Proto-Indo-European *ǵn̥h₃-tis, an action noun of the root *ǵneh₃- (“to recognize, get to know”); by surface analysis it is formed from γιγνώσκω (gignṓskō, “to know”) with the suffix -σις (-sis).[2][1] NIL sets beside it Lithuanian pažintìs (“knowledge”) and Gothic 𐌲𐌰𐌺𐌿𐌽𐌳𐍃 (gakunds, “persuasion”).[2] The verb matches Latin nōscō, and the root is in Sanskrit ज्ञात (jñātá-, “known”), Old Church Slavonic знати (znati) and Gothic 𐌺𐌰𐌽𐌽 (kann).[3]

Earliest recorded meaning

The first record is a fragment of Heraclitus on “the knowledge of visible things”.[4][5] Philolaus speaks of nature admitting divine, not human, knowledge.[5]

Semantic evolution

In Classical prose it is knowledge and understanding: Plato sets it against ignorance, Aristotle calls perception a kind of knowledge, and Thucydides uses it for recognizing a person.[4][6][5] In the Attic orators it is a legal term, the investigation of a case and the court's or arbitrator's finding.[4][6] Isocrates and Aeschines use it for acquaintance with someone.[6]

In the New Testament it is knowledge of God and his ways, and in Paul a higher spiritual knowledge.[7][4] Christian writers used it for a higher knowledge of spiritual things, and English took gnosis from them, recorded from 1703.[8] The medieval vernacular kept γνώσις, and Modern Greek γνώση (gnósi) is knowledge, partly a learned word and partly inherited through medieval Greek.[9][10]
