Modal Operators: modal operators are symbols for expressing possibility and necessity. These operators do not belong to classical logic, but fall into the field of modal logic. Their placement at the beginning or in the course of formulas determines the relative strength of statements that can be obtained from the interpretation of these formulas. See also range, stronger/weaker, modal logic, possible worlds.
