The COVID-19 pandemic has significantly impacted global healthcare systems. Since its onset in late 2019, an extensive research effort by scientists, researchers, and healthcare professionals has aimed at understanding and mitigating the impact of this highly transmissible and potentially deadly virus. An integral part of this effort has been developing a comprehensive terminology that encompasses a wide range of terminological constructs to denote different facets of the virus, its modes of transmission, preventive measures, therapeutic interventions, and related public health strategies. The development of COVID-19 terminology was a multidisciplinary effort, drawing on expertise in fields such as virology, epidemiology, immunology, public health, and healthcare management. It required identifying and defining new terms to describe novel phenomena and concepts associated with the virus and the adaptation and recontextualization of existing terminology. The resulting terminological framework has facilitated professional discourse within the scientific community and has also permeated public communication, sustainably shaping the collective discourse surrounding COVID-19.The importance of terminology research in the context of a pandemic is undeniable. Effective communication is essential in challenging times. Accurate and standardised terminology plays a vital role in facilitating clear communication that unambiguously links the various stakeholders involved in managing the crisis. In the context of the COVID-19 crisis, terminology research was important in several ways. Firstly, such research has focused on identifying and documenting the terminology used by scientists and experts in their research papers, clinical guidelines, and public health recommendations to describe the virus, its transmission, symptoms, and treatments. This research aimed at harmonising and standardising terminology to streamline communication between different stakeholders in scientific and healthcare communities. The active involvement of the research community and collaboration between experts, health organisations, and international policy-making bodies such as WHO has been crucial in this process, for example in facilitating and coordinating terminology for vari-
