Forms

αἵρεσῐς (haíresis) f (genitive αἱρέσεως or αἱρέσῐος); third declension[1]

Etymology

It is derived from αἱρέω (hairéō, “to take, (middle) to choose”), with the suffix of action nouns -σις (-sis).[1][2][3] Beekes knows no etymology for the verb, which uses ἑλεῖν (heleîn) as its aorist.[3]

Earliest recorded meaning

Herodotus uses it for the taking of a city, such as Babylon.[4][5] Pindar already has the sense “choice”, and Aeschylus has αἵρεσιν διδόναι, “to give someone the choice”.[4][5]

Semantic evolution

The two senses follow the two voices of the verb: the active “take” gives “capture”, the middle “take for oneself, choose” gives “choice”.[4][3] In Classical Athens it was also the election of magistrates, which Aristotle opposes to selection by lot.[4][6]

In Hellenistic Greek it came to mean a chosen course or principle, and then a system of belief and those who hold it: Polybius and Diodorus use it for a philosophical school, and Diogenes Laertius lists the “schools” of philosophy.[4][6][7] Josephus and Acts call the Pharisees, the Sadducees and the Essenes, and even the Christians, haireseis.[7][4] In Paul it means a faction, and in Ignatius and later Christian writers a heretical sect.[7]

Latin borrowed it as haeresis, Gothic and Old Church Slavonic took it too, and medieval vernacular Greek used it for a religious heresy and a bad habit.[1][8]
