The analysis is a contribution to contemporary linguistics, particularly the theory of syntax, semantics and pragmatics. Within the theoretical framework of predicate-argument syntax (also known as semantic syntax), the author analyses the role of the adjective as an adjunctive predicative expression. The aim of the research is to create a description of an adjective which could be prospectively useful as a point of departure for analyses of phenomena analogous from the communication point of view in other languages. The book contains a rich text material and a large number of valuable pragmatic insights into Polish nominal syntagmas with an adjective.
