  • 4th-century AD Koine: /paˈra.ny.a/[1]
  • 10th-century Byzantine: /paˈra.ny.a/[1]

Forms

πᾰρᾰ́νοιᾰ (paránoia) f (genitive πᾰρᾰνοίᾱς); first declension[1]

Etymology

It is from Ancient Greek παράνοος (paránoos, “deranged, mad”) with the abstract suffix -ία (-ía).[1] The adjective is formed from παρά (pará, “beside, beyond”) and νόος (nóos, “mind”), and the noun is close to the verb παρανοέω (paranoéō, “to be deranged”).[2][3][4]

Earliest recorded meaning

The first record is Aeschylus' Seven against Thebes, in the sense “madness”.[5][6][7]

Semantic evolution

In tragedy and medicine the word meant derangement or madness: Euripides uses it in the Orestes, and the Hippocratic Prognostic of mental disorder in illness.[5][7] In Athens it was also a legal term: a suit for παράνοια could be brought to establish that a citizen was too insane to manage his affairs, an action to which Aristophanes refers in the Clouds and which Plato and Aristotle mention.[5][8][9] Aristotle also uses the plural for fits of madness.[5]

In later Greek the word meant folly as well as madness; it occurs in Plutarch and Philo, and as a variant reading in the Second Epistle of Peter.[4] Hesychius glosses it as “arrogance”.[10]

In the 19th century the word was revived in Latin form as a psychiatric term, which gave English paranoia in 1848 (paranoea from 1811).[2][11] Modern Greek παράνοια (paránia) continues the ancient word and the psychiatric sense of New Latin paranoia, and also means irrational behaviour in general.[11][12]
