The unique work in its subject matter, genre and language has been prepared during the first wave of the coronavirus epidemic. The theoretical background of the author’s research work is perfectly adjusted to Patyi’s „university triangle” model, which basically illustrates the operation of the university in a triple system of the activities (research–education–curriculum development) and Paavola and Hakkarainen’s trialogical model (2005), which creates an opportunity with the competence of cooperation to develop students’ creativity, to keep their motivation at a high level, the competencies demanded by the labour market, and to provide experiential teaching-learning. Using corpusbased dictionary method a questionnaire survey was used with closed and open questions among the students who have been learning English for law enforcement at the University of Public Service, Faculty of Law Enforcement. The author’s acquaintances registered on Facebook social media platform were also involved in the research. The 96-page collection of words and phrases collection based on the theoretical background we have introduced before involves 403 English words, word phrases, neologisms and their definitions related to the coronavirus epidemic and COVID-19 situation during the first wave.
