The subject of this thesis paper is Neologisms coined during the COVID-19 pandemic. Not only has the COVID-19 pandemic transformed the entire world in terms of public health and global dynamics, but it has also had a major impact on language and communication. This thesis explores the phenomenon of neologisms that emerged during the pandemic. The main goal of this paper is to identify the neologisms that have surfaced during the pandemic and the role they have found in everyday language. The question of their position in the language pertains to whether these neologisms will endure and become commonly used or fade into obscurity. A research study was conducted using a specialized corpus in Sketch Engine to obtain the results. Key findings revealed that terms directly connected to the disease, such as COVID-19 and SARS-CoV-2, are likely to endure. Neologisms like new normal, COVIDrelated, and self-quarantine displayed usage fluctuations. Conversely, terms like disinfodemic, moronavirus, and coronacoma had limited impact and appeared sparingly in the corpus. This paper will contribute to the understanding of the status and significance of neologisms arising during the COVID-19 pandemic, providing insight into lexical changes and the evolution of neologisms over time.
