The subject of the study are marker words, linguistic methods that reveal linguistic signs of a discourse that has a meaningful and semantic focus on receiving or transferring values for the actions of the recipient (inaction), in favor of the giver. The purpose of this work was to conduct a communicative analysis of corrupt speech behavior in the text–dialogue: to accept illegal remuneration for actions (inaction) in the service in order to obtain valuables in the event of an agreement between the specified persons.The main task of the linguistic and forensic examination of anti-corruption cases is to establish the event by its speech representation: it is required to prove that the dialogue is about the transfer of funds. To solve this issue, it is necessary to conduct a communicative analysis of the text-dialogue. The research methodology is related to the communicative analysis of texts-dialogues with signs of corruption content, based on the works of D.L. Karpov, "on the theoretical and practical works of A. N. Baranov, K. I. Brinev, E. N. Galyashina, M. A. Grachev, I. A. Sternin, etc., devoted to cases related to corruption. The scientific novelty of the work lies in the use of a communicative approach within the framework of text-dialogue analysis, logical-semantic and functional-stylistic analysis. The analysis of the expert study of the text-dialogue on anti-corruption cases is presented, the conceptual framework is developed. As a result of the study, it was concluded that the main task of linguistic expertise in anti-corruption cases is to establish an event by its speech representation through the use of a set of semantic and pragmatic techniques of discursive analysis, which allows us to clarify the signs of conversational dialogue that are significant for the legal qualification of speech crimes.
When conducting a communicative analysis of a corrupt text, it is important to identify signs of corrupt speech behavior. When analyzing a communicative corruption situation, it is necessary to consider the speech strategies and tactics of the participants in the dialogue, which ultimately allow us to determine the true intentions of the communicants aimed at achieving a communicative goal.
