### How are connectives used to connect two logics?

A Logical Connective is a symbol which is used to connect two or more propositional or predicate logics in such a manner that resultant logic depends only on the input logics and the meaning of the connective used. Generally there are five connectives which are −. OR (∨) AND (∧) Negation/ NOT (¬) Implication / if-then (→) If and only if (⇔).
