Business discourse is unidentifiable apart from its own specific metatext that is to be treated as a text which incorporates a paradigm of previously produced texts for similar (or identical) pragmatic purposes under similar (or identical) social conditions in order to perform intended mutually intelligible communicative functions. The purpose is to establish a relation between the communicative types of business texts and dominant linguistic strategies that are applied in order to realise the communicative functions of informing, persuasion, and reporting in institutional business communication.
