The topic of this thesis is the description of stylistic features of communication texts on social networks. The aim of the paper is to describe the most important features of communicative texts on social networks and in chatrooms and to mention the functional styles of the Croatian standard language, to describe the conversational functional style and to present its linguistic features. The analysis of stylistic features on selected examples of communication texts taken from social networks shows the main features of online communication and communication texts. From the analysis, it can be determined that communication texts consist of numerous anglicisms, dialectics, jargonisms and vulgarisms. An important part of communication texts is made up of emoticons that replace part of the text or stand as an accompaniment to the text. They are accompanied by stylish figures and expressive expressions. Abbreviations of English and Croatian expressions and words that can be said to have largely entered daily oral communication are also visible. Also, communication texts are marked by frequent violations of spelling and grammar rules and standard language norms. Online communication is informal, relaxed and shows a high degree of freedom of speech, and it can be concluded that communication texts on social networks abound with features of a conversational style.
