The article describes the results of a two-fold experiment aimed at identifying the active vocabulary of Bulgarian predicatives used to express the state of the subject in the impersonal construction including the dative of experiencer (Obidno mi e; Radostno mi e). The vocabulary of 320 items has been tested on native speakers of Bulgarian to obtain a ranked word list further correlated with a sample list from the Bulgarian National Corpus. The alignment of the two lists allowed to estimate the openness and productivity of the model, as well as the volume and structure of the Bulgarian predicative vocabulary.
