Pronunciation

  • 5th-century BC Attic: /ɡnɔːs.ti.kós/[1]
  • 4th-century AD Koine: /ɣnos.tiˈkos/[1]
  • 10th-century Byzantine: /ɣnos.tiˈkos/[1]

Forms

γνωστῐκός (gnōstikós) m (feminine γνωστῐκή, neuter γνωστῐκόν); first/second declension[1]

Etymology

From γνῶσις (gnôsis, “knowledge”) (or the stem of γνωστός (gnōstós, “known”)) and the suffix -τικός (-tikós).[1][2] Both belong to γιγνώσκω (gignṓskō, “to know”).[1]

Earliest recorded meaning

Plato's Statesman divides all knowledge into the practical and the purely theoretical (γνωστική); the word is the Platonic term for theoretical science.[3][4][5]

Semantic evolution

Aristotle and the later philosophers (Plutarch, Proclus) used it for what is able to know: cognitive powers and states of the soul.[3][5]

In Christian writers it took a religious sense: Clement of Alexandria calls the perfect Christian, whose faith has become knowledge, “the gnostic”, while Irenaeus and Hippolytus use the noun for the members of the sects that claimed a secret knowledge, the Gnostics.[3] The Coptic texts borrowed it.[6]

In Medieval and Modern Greek γνωστικός (gnostikós) means sensible, prudent; in learned use it also means cognitive, and a second word, from the medieval name of the Gnostics, means “Gnostic”.[7][8][2]
