This paper discusses the relationship between grammar and pragmatics from the point of view of historical grammar writing. Language system provides a set of possibilities of variation, the selection among which is mainly directed by pragmatic factors in that certain types of texts may prefer certain syntactic phenomena. In turn, syntax thus influenced by language use may become the source of new grammatical changes. That is how language use and language system are integrated: hence, no opposition between pragmatics and grammar is worth pursuing.
