So, every exception set S that is not a subset of C(={b}) makes the prejacent statement false, i.e. makes it so that some (NPᵂ–S) (VPᵂ)=0.
Where it comes from
Multiple origins. Borrowed from Middle French prejacent (“previously existing”) during the sixteenth century. Also attested in twelfth century British sources, from post-classical Latin praeiacens (“situated before”).
