The focus of this research is on the morphological, semantic, and typographic features of youth language on social media. The goal is to explore new pragmatic uses of these features and determine how they differ from past practices. Understanding youth language on social media requires an understanding of the features of computer-mediated communication, which directly reflect the features of this type of youth language. The morphological features examined in this study are abbreviations and initialisms, which are primarily used for linguistic economy, however, initialisms also serve to express intensified emotions or to cover up expletives. A further analysis of semantic changes is conducted to determine the motivation behind the observed semantic extensions, and it was concluded that in the analyzed corpus the new meanings of words are used mostly to express strong emotions, attitudes, and reactions, both positive and negative, but also to create and maintain an in-group feeling. Young people get involved in language play with others because of the feeling of belonging to that group and the development of their own identity. Youth create innovative language as a result of feeling included in the community. The analysis has also revealed that emotionally laden language is pervasive on social media. Some of the ways young people express their attitudes and emotions are using different means of intensification, e.g., adverbial intensifiers, but also typographic features, such as caps lock, use of special characters, exclamation points, and letter repetitions.
