Forms: 1500s– scission; Scottish pre-1700 scissione.

Origin: Of multiple origins. Partly a borrowing from French. Partly a borrowing from Latin. Etymons: French scission; Latin scission-, scissio.

Etymology: < (i) Middle French, French scission action of cutting or dividing (a1365), division, cut (1488), split, division in a previously united body of people, state, etc. (1517), schism (1739), and its etymon (ii) post-classical Latin scission-, scissio action of dividing (Vulgate), separation (4th cent.), dissent (8th cent.), schism (from 12th cent. in British and continental sources) < classical Latin sciss- , past participial stem of scindere scind v. + -iō -ion suffix¹.

1. Division of a previously united body of people into mutually opposing parties; a split, a schism.In quot. 1443: spec. = schism n. 2b.
