The main goal of the research presented in the article was checking models of 'joy-like' feelings that can be found in textual material of medium PWN Polish Language Corpus, where the noun 'radosc' (joy) was mentioned almost 5000 times. As the analysis shows, there are five major models of joy: (I) - 'factual' ('reactive') joy, (II) - joy 'felt in action', (III) - 'festive' joy, (IV) - 'comic' joy and (V) - joy 'without any actual reason'. Moreover, among detailed variants of the models, there are: (A) - joy 'because of someone else's being unlucky', (B) - 'rational' and/or 'conventional' joy, (C) - 'sensual' joy and (D) - 'sacrificial' joy. Such a great number of models may be one of the reasons why lexicographers find it difficult to make a clear definition of 'radosc', which is why they often choose the method of description of the meaning using a range of synonyms. The similarities and differences among the models prove that, beside the repetitive aspect of the positive evaluation of the reason for the feeling, and the feeling itself, a significant role in conceptualization of joy belongs to the quality of activeness of the subject, which should be also exposed in lexicographic definitions.
