Erasure (logic)

In mathematical logic, a logical system has the erasure property if and only if no subset of the propositions can be added to another subset of the propositions to refute a consequence.

For instance, if proposition A means "the store is open from 8:00 to 22:00" and proposition B means "except Tuesdays", the system AB does not have erasure.
