Pronunciation

  • IPA (5th-century BC Attic): /a.pʰo.riz.mós/[1]
  • IPA (4th-century AD Koine): /a.ɸo.rizˈmos/[1]
  • IPA (10th-century Byzantine): /a.fo.rizˈmos/[1]

Forms

ᾰ̓φορῐσμός (aphorismós) m (genitive ᾰ̓φορῐσμοῦ); second declension[1]

Etymology

It is derived from ἀφορίζω (aphorízō, “to mark off, separate”) with the suffix -μός (-mós).[1] The verb is formed from ἀπο- (apo-, “off”) and ὁρίζω (horízō, “to bound, define”), from ὅρος (hóros, “boundary”).[1][2]

Earliest recorded meaning

Critias already uses it for a pithy sentence, an aphorism, and Aristotle's Categories for determination.[3]

Semantic evolution

Its literal sense was the marking of boundaries, a land survey, as in papyri from the 2nd century BC and Delphic inscriptions.[4][3] Theophrastus uses it for separation or distinction, for the attainment of definiteness, and for a fixed rule; from “definition” came “a short definition”, and so the pithy sayings of the Hippocratic Aphorisms, a term Philo and Hermogenes use.[3][4] The Septuagint uses it for an offering set apart, and John Lydus for banishment, translating Latin relegatio.[5][3]

Latin borrowed it as aphorismus.[1] In Christian Greek it became the church's sentence of separation, excommunication, which is its main sense in Modern Greek αφορισμός (aforismós); as a learned word it is also a dogmatic pronouncement made without proof.[6]
