Text is a linguistic unit of communication in which linguistically expressed conceptual units are connected in different conceptual structures. The conceptual construal of things, events and relations is structured on the basis of a variety of cognitive and communicational options. These choices form discourse schemas, partly in a culturespecific way. There is a dynamic relationship between schema and instantiation. The volume approaches these questions from a functional perspective, where the processual nature of discourse is as important as its structural character. The volume has two parts: the first one presents theoretical papers, the second deals with certain discourse types, and some linguistic features that characterize specific discourse types.
