The aim of this article is to discuss and analyse the meaning and various forms of grotesque in Polish literature of the interwar period. The author of the paper would like to focus on the use of grotesque by such Polish modernist writers and playwrights as Witold Gombrowicz, Bruno SCHULZ and Stanisław Ignacy Witkiewicz. The article aims at examining different forms of this literary genre (humour, parody, absurd), especially its linguistic aspects and at showing their similarities and differences. In the scrutiny of grotesque the author of the paper will refer to various critical schools and approaches in Poland, particularly the contemporary literary and linguistic studies.
