The aim of this paper is to explain the concept of phrasemes through different methodological approaches and theoretical determinants as well as to investigate the presence and function of phrasemes in Jaša Dalmatin, potkralj Gudžerata. The motive for the creation of this paper is the tendency to actualize the author's underappreciated novel, which undeservedly remained in the shadow of the best works. The paper analyzes phraseology as a linguistic discipline to which phrasemes are the subject of research and as a way of expression characteristic of a certain writer, in this case Ivana Brlić-Mažuranić. Phrasemes in a narrow sense and phrasemes in a broad sense are included in the analysis, and the scope of phrases includes the type of three-part division. Different characteristics and definitions of phrasemes, the semantic aspect of phrasemes, their division with regard to origin and style, and different interphraseme relations are analyzed. In the second part of the paper, the biography of Ivana Brlić-Mažuranić and her literary work are studied, where the phraseology of a given novel is also described. At the end of the paper, an article with phrases from the novel is presented, the meanings of which are taken from the Hrvatski frazeološki rječnik and the Hrvatski jezični portal.
