Inertextuality is a stylish procedure which is widely represented in modern children's literature. This procedure contributes to the development of the modern Croatian fairy tale, which is the corpus of this research in this final thesis. The paper highlights are the division by Pavle Pavličić and Dubravka Oraić-Tolić into conventional and unconventional type, i.e. into illuminative and illustrative type of intertextuality. The paper deals with the forms and procedures of intertextuality in the fairy tale Pisac i princeza by Sunčana Škrinjarić and Alisa kod Andersena by Mirjana Mrkela. In those texts intertextuality became a fundamental procedure of plot development and a fundamental stylish procedure. In addition, intertextuality enabled the correlation of classical and modern fairy tales and thus children were enabled to better receive classic stories, which is also the case with the mentioned modern fairy tales that are the subject of research in this paper.
