The way we communicate with our environment is changing daily under the influence of various factors. Language barriers are shifting, and seemingly incompatible cultures are merging, primarily due to technological innovations and social media, which allow people from different parts of the world to connect in a comprehensive and dynamic online community. Under such influence, people easily accept foreign cultural, social, and linguistic characteristics. The first part of this paper explores the emergence and development of social media and illustrates how this development has culminated in the creation of an unlimited number of social networks that are now used for both business and private purposes. Also, the paper highlights the features of language on social platforms, focusing on the adaptation of language to the speed and limitations of online communication. The paper describes the unstoppable breach of English words and loanwords that have become a integral part of online communication, as well as the use of abbreviations and emoticons, which are increasingly replacing nonverbal face-to-face communication. Furthermore, the paper provides a brief overview of the importance of preserving linguistic purism and the purity of the Croatian standard language, emphasizing the need to find a balance between new forms of communication and the standard language. The final chapters present a concise overview of the development of today’s most popular social networks and their linguistic peculiarities. Linguists, institutions, organizations, and individuals all have a responsibility to monitor language changes to prevent problems and misunderstandings in the communication that connects us daily.
