apostasy

The word 'apostasy' has a direct lineage from ecclesiastical Greek apostasia, meaning "a defection or revolt." This Greek term is itself a compound of apo- ("away from") and stasis ("a standing, position"). The literal image is of "standing away from" or "a removal from" a previously held station, which perfectly encapsulates the modern sense of a formal renunciation or abandonment of one's faith or allegiance. It entered English in the late 14th century via Old French apostasie and ecclesiastical Latin apostasia, carrying its core meaning of religious defection, which has since broadened to include the abandonment of any strongly held principle or party.
