What is pragmatic theory? It has proven difficult to provide a satisfactorydefinition of pragmatics due to the complexity of the phenomena involved. The modern use of the term can be traced back to Charles Morris (1938) who defined pragmatics as the study of “the relation of signs to interpreters”. He distinguished three fields of study: (1) syntax, the study of “the formal relations of signs to one another”, (2) semantics, the study of “the relations of signs to the objects to which the signs are applicable”, and (3) pragmatics, the study of “the relation of signs to interpreters”
