|Reference, in philosophy: relation of a linguistic expression or action to a real object. Reference presupposes the existence of this object. An expression, which corresponds to no object, has no reference, however, may have a meaning. See also unicorn, Pegasus.|

Reference: words such as "and", "or", "if", "the", "is", "not" have absolutely no reference! "If does not" mean an event and there is no property of if-not-being. These words have neither extension nor intension. They have a grammatical function.
