The author analyses prepositional constructions along the lines of Goldberg’s cognitive construction grammar. The paper starts with a discussion of Goldberg’s definition of a construction and the main theoretical assumptions of her approach. The semantic analysis of a construction is based on its contextual meaning as related to the speech event and then subsequently related to its conceptual frame, that is, its predicate-argument structure. Such an analysis of prepositional constructions allows a much wider scope of a construction than has been so far considered. It also allows the analyst to identify an abundance of a series of phrasemes which have not been accounted for even when analysing a single particular preposition (the Polish preposition ‘w’: ‘in’) in dictionaries or the studies of prepositions.
