Grammar of medical examinations, treatment and procedures

The article examines the competition of professional terms and colloquial terminoid that arise in the current medical discourse. The study was conducted using the corpus method with elements of cognitive, semantic-syntactic, comparative-historical and content analysis based on the material of the Russian National Corpus. The object of consideration was high-frequency clichés characteristic of the dialogue between a doctor and a patient in key situations of diagnostics, treatment and recommendations, and the subject of their normativity/non-normativity, stylistic coloring and attitude to professional or everyday speech. The aim of the study was to determine the status of competing terminological variants and assess the dynamics of their entry into common usage. Normative designations of medical examination, taking drugs and procedures by patients, injections and preventive vaccinations were determined. The results showed that professional clichés have a long history of use, while colloquial variants have emerged and spread only in recent decades. Rapid spread is facilitated by inclusion in significant communicative contexts and replication by social networks and mass media. The study revealed the influence of everyday speech of patients on professional medical discourse and allowed to describe the process of transformation of folk medical colloquialism into an element of general medical jargon
