Modern social networks are a significant factor in transforming communication processes, contributing to the formation of a unique network language. The combination of oral and written communication elements ensures rapid information transmission, inevitably influencing linguistic norms. The given article explores the role of social networks in language transformation, particularly their impact on vocabulary and the functioning of network language.The paper analyzes the concept of “social network” and identifies key categories of vocabulary innovations actively used in online communication: abbreviations, acronyms, and neologisms. Examples of their spread in popular social networks (Twitter, Instagram, Facebook) are provided. For instance, Twitter has enriched the English language with lexemes such as attwicted, twitamin, egotwistical, and retweet. Among the most common abbreviations used on this network are Ab/abt, BFN, HAND, etc. Thanks to Instagram, acronyms such as OOTD (Outfit of the Day) and WCW (Woman Crush Wednesday) have become widespread. The name of the social network Facebook itself is a commonly used abbreviation (FB).Additionally, Facebook has contributed to the establishment of abbreviations such as IMO (in my opinion) and TBT (Throwback Thursday) in the English language.The article examines their impact on traditional linguistic norms, particularly changes in the lexical composition of English and the tendency toward simplified spelling rules. The research methodology includes a descriptive method, comparative analysis, linguistic and stylistic analysis, contextual analysis, and statistical methods. The study analyzes 300 lexical units selected through the continuous sampling method. It has been found that the majority of network neologisms originate from English due to globalization and the dominance of English in digital communication. The study results demonstrate that network language is a dynamic phenomenon that continuously expands the vocabulary.Popular social networks generate unique neologisms and abbreviations, which gradually integrate into users’ speech and become embedded in their communicative practices.
