A cognitive-pragmatic analysis of metalinguistic negation;

As a kind of marked negation,metalinguistic negation is usually marked by the double-sentence structure,consisting of a basic negative sentence plus another positive or negative sentence.

Horn divided negative sentence into two kinds:descriptive negation and metalinguistic negation during 1980s.

And negation in our natural languages turns out to be so complicated that the traditional unitary account proves ineffective either for negation in general or for the so-called metalinguistic negation in particular.

Instead, I will restrict my discussions to a cognitive study of metalinguistic negation, a special kind of negation.

As an important part of negation and natural linguistic phenomenon, metalinguistic negation has drawn more and more attention of researchers in recent years; however it is noteworthy that much attention has been contributed to describe MN from semantic and cognitive point of view, few endeavors have been made on explaining MN from pragmatic perspective.
