Etymology

From Middle English heresie (Middle English her(esie) + -esy), from Old French heresie (modern hérésie), from Latin haeresis, from Ancient Greek αἵρεσις (haíresis, “choice, system of principles”), from αἱρέομαι (hairéomai, “to take for oneself, to choose”), the middle voice of αἱρέω (hairéō, “to take”), possibly from Proto-Indo-European *ser-; see also Welsh herw (“theft, raid”), Ancient Greek στερέω (steréō, “to deprive of”). Displaced native Old English dwild.
