This research project delves into the multifaceted world of English abbreviations and acronyms, examining their origins, evolution, and impact on modern communication. The study will encompass a detailed linguistic analysis, exploring the morphological, syntactic, and semantic aspects of these abbreviated forms. Furthermore, it will investigate the cognitive processes involved in their comprehension and production, considering factors such as context, prior knowledge, and frequency of use. The project aims to provide a comprehensive overview of the phenomenon, addressing various domains, including formal and informal registers, scientific and technical fields, and online communication platforms. The research will employ both qualitative and quantitative research methods, including corpus analysis, surveys, and experimental studies, to gather and analyze data. The findings will contribute to a deeper understanding of the dynamics of language change and the challenges and opportunities presented by the widespread use of abbreviations and acronyms in contemporary English.
