Understood as the linguistic representation of the action of an animated subject, agentivity in French emerges from a variety of linguistic structures that only a manual inspection of the corpus can uncover. Having demonstrated this principle, this paper then examines the agentive and patient posture of the health care personnel as expressed by the JE and ON structures, with the aim of reporting on the degree of agentivity verbally expressed by more than thirty AP-HP health-care personnel who were interviewed at the end of the first year of Covid-19.
