From a theoretical point of view nearly all of the suggested title components are conceptually problematic. What does it mean when something is called an institution? What is an institutional or non-institutional, a political or a nonpolitical speech act? How can these acts be defined and how can certain linguistic occurrences be identified as realisations of these acts? It cannot be the task of this article to unfold critically all these concepts. However, it is necessary to clarify how these concepts are used here. This is the main perspective of the first section: concept clarification as a preliminary step to the collection of data. Then, in the two next sections, candidates for institutional speech acts (section 2) and non-institutional speech acts (section 3) are named and described.
