"Although some of the logicians working in term logic have very complicated treatments of negation, we can see the origin of the modern conception in the extensional tradition as well. In Boole and most of his followers, the negation of a term is understood as the set theoretic complement of the class represented by that term. For this reason, the negation of classical propositional logic is often called ‘Boolean negation’."

From Middle English negacioun, from Old French negacion, from Latin negātiō (“a denial; negative word”). Morphologically negate + -ion.
