The study offers an analysis of three grammatical constructions specifically employed in direct performance of directive speech acts in Polish. Constructions of this type have not yet been widely analyzed, as research pertaining to the relation between the grammatical structure of an utterance and its pragmatic effects has focused mainly on indirect speech acts. The study combines a discussion of a wide range of corpus examples with a detailed analysis of hand-picked examples situated in specific contexts. The aim is to show how the grammatical make-up of a construction functions with contextual factors to bring about a range of pragmatic effects pertaining to the speakers' interaction and their interpersonal relation. The framework of the study is the theory of cognitive grammar.
