PRIMITIVE
(Negation means that a proposition has the opposite truth value.)
negative (polarity) (SEM) = indicates that the situation expressed in the utterance is false. Example: Kit didn’t find his glasses expresses that Kit finding his glasses is false. This is the prototypical use of negative polarity. Negative polarity may be used to reject other aspects of the construal of the situation expressed in the utterance, as in Kit didn’t like the movie – he loved it! (where the degree expressed by like is the information rejected).
