The paper aims to overview some typical principles of communicative language use in a cognitive pragmatic approach applying a reductionist method in order to demonstrate that the well-known principles can be reduced to a very general rationality (economy) principle. After briefly reviewing the principles the paper re-evaluates them and provides a new classification of them relying on the definition of ostensive-inferential communication. The principles which can be divided into rationality and interpersonality principles are really principles of effective information transmission on objects and selves. They refer to two kinds of language use: informative and communicative ones. The only principles valid for only communicative language use are the communicative principle of relevance and the principle of communicative intention suggested in the present article. Finally, the paper reduces all rationality and interpersonality principles to a very general rationality principle, i.e., the cognitive principle of relevance.1. Introduction
AimsThe present paper aims to explore some of the typical principles of communicative language use. As a starting-point for the investigation, I will define communicative language use within the scope of pragmatic competence. Then I will give a brief overview of the possibilities raised in the linguistics literature of how to interpret the term principle, as well as select the relevant interpretations fitting in with the aims of this paper. After completing these tasks, I will have three main goals: (i) to choose, briefly characterize and evaluate some typical communicative principles treated by the pragmatics literature; (ii) to re-evaluate the chosen principles and provide a new classification of them relying on the definition of ostensive-inferential communication, and (iii) to demonstrate that all * The research reported here was partly supported by the Bolyai János Research Grant.
