Biconditional: notation ↔; a statement that is true if the two sides have the same truth value ("true" or "false"). The biconditional (also bisubjunction) is part of the object language. Contrary to that is equivalence (⇔) which belongs to meta language. A biconditional that is always true is an equivalence.
