ABSTRACT

Logical relation between classes of sets of elements in which it is the case that every element of class A is also an element of class B: All brothers (=class A) are male relatives (= class B). In the semantic aspect of relations between meanings ( semantic relation), inclusion often corresponds to hyponymy, and in propositional logic to implication. ( also formal logic, set theory)
