The subject of this paper are picture books, that is, the language in contemporary picture books. Given its importance as a first book, a picture book has to fulfill the goals and functions that will develop the child's sense of art and literature, enrich his vocabulary, and encourage the child to read, think, connect and awaken various emotions. Different functions of picture books, such as information-education, cognitive, experiential, aesthetic, fun and spoken-linguistic function, help the child make connections between things and phenomena through images and text adapted to their age, to develop thinking, to make connections associated with family and society, and to come to know about the correctness of their cognitions and attitudes. Picture books serve the child as a game and fun through which they simultaneously acquire knowledge. The aforementioned was achieved in the selected picture books by Nada Horvat that were analyzed. Books “Mica Šminkerica i njezini šeširi”, “Mica Krotiteljica Oblaka”, “Mica Debeljuca-Mršavica” and “Mica Lažljivica” are written in a simple language that contains common stylistic (epithets, metaphor, hyperbole, personification) and lexical means (colloquialisms, jargon, phrases) appropriate to children's age. In addition to the importance of choosing appropriate language means, the work also emphasizes the humorous tone of text, whose function is to facilitate the reception of formatted content in children.
