In this thesis, we are analyzing the semantic roles, more specifically, the meaning of accusative. The research material is composed of the modern Croatian drama „Hana i Hana“ (2009) from the author Mira Perić Kraljik, which was released in the drama anthology „Žene u dijelovima“. The complete breakdown of the semantic role of the accusative will be generally structured after the classifications in the „Gramatika hrvatskoga jezika za gimnazije i visoka učilišta“ (Croatian grammar for high schools and colleges) written by Josip Silić and Ivo Pranjković. In the introduction of the thesis, we are given a short recap of the cases, the Croatian case system and the important role of the cases which are mentioned by the known linguistic experts and scholars in their scientific research papers. A few lines are dedicated to the functional styles of the Croatian language as well, more specifically between the similarities and differences between them. This research material is composed of dramatic texts and as such a special attention is given to the dramatical subgenre of the literary and artistic genre. In the research part of this thesis, we have specific words regarding their variability and stability. More specifically lexical words and functional words are determined, the cases, prepositions with accusative and the representation of the accusatives semantic roles. The identification of the accusatives meaning within a drama can be used for further research and studies regarding the meaning of the cases, to ensure the high result reliability for further research a larger number of modern dramatic texts should be included. However, the data given by this research can be used as an incentive for new research to come for all those who want to learn something more about the meaning of the cases which have a large role, not only in the research of the Croatian language but also in mastering the Croatian language.
