Language exists and develops due to intralinguistic and extralinguistic factors. In connection with the global situation, most world dictionaries have a common feature – the emergence of new terms characterizing the spread of the pandemic, which has had a significant impact on the development of the human language. Since 2020, the term “lockdown”, previously used only in prison terminology, has begun to emerge in common vocabulary. The term is gaining popularity and is often applied by media. However, the semantics of this term is not fully revealed. In this regard, our research interest lies in the study of “lockdown” from the point of view of linguistic science in general and the achievements of corpus linguistics in particular. For the analysis, we reveal its origin and formation, present the definitions of “lockdown”, proposed by world dictionaries, and the search results in the corpora of the Kazakh, Russian and English languages. Additionally, we carry out a corpus analysis of the search term in the research corpus created with the #LancsBox program. Thus, we receive up-to-date data on the use of the term “lockdown” in the current Kazakh linguistic environment. The results cover concordance lines, occurrence, frequency lists, linguistic markings, and the relevant context. Key words: corpus tool, terminology, corpora, term, lockdown.
