CONTRAPOSITIVE

Etymology

Noun

contrapositive (plural contrapositives)

(logic) The inverse of the converse of a given proposition.

Usage notes

• From a proposition, its inverse, its converse, and its contrapositive are derived as follows

• If a proposition is true then its contrapositive is, too. Thus, if the statement "If I'm Roman, then I can speak Latin" is true, then it logically follows that the statement "If I can't speak Latin, then I'm not Roman" must also be true.
