abscissionn.

Brit.

/əbˈsɪʃn/,

/abˈsɪʃn/, U.S.

/æbˈsɪʒ(ə)n/

Forms: 1500s– abscission, 1800s– abscession (irregular).

Origin: Probably of multiple origins. Probably partly a borrowing from Latin. Probably partly a variant or alteration of another lexical item; modelled on a Latin lexical item. Etymons: Latin abscission- , abscissio ; abscision n.

Etymology: Probably partly < post-classical Latin abscission-, abscissio action of tearing up or uprooting (4th cent.), excommunication (5th cent.; < classical Latin absciss- , past participial stem of abscindere abscind v. + -iō -ion suffix¹), and partly an alteration (after classical Latin absciss-) of abscision n. Compare Anglo-Norman (rare) abscission amputation (late 13th cent. or earlier in a medical context; compare French abscission, from late 18th cent. onwards).In post-classical Latin, abscissio and abscīsiō abscision n. are frequently confused. The form abscession probably results from association with abscession n. or its etymon classical Latin abscēssiō.

a. The action or process of cutting off or separating something; an instance of this.
