Abstract. This paper evaluates the potential of linguopersonology one of the most promising fields of modern linguistic research and its closely related discipline, linguodiagnostics. In her study, the author employs descriptive, contextual, comparative, semantic field and extralinguistic analysis methods, as well as the combined use of biographical and cognitive analysis approaches, which are widely applied in literary text studies. The literary texts examined required both descriptive and contextual interpretation to substantiate the author’s standpoint, while the influence of individual biographical features on worldview and linguistic identity was also explored to characterize the author’s linguistic worldview. The contextual expressive potential of individual words and expressions was analyzed through the study of their semantic fields. As reference material, the texts of Franz Kafka’s works were used. The research holds scientific value as one of the first analyses in this direction. The results obtained indicate broad prospects for the further development of linguodiagnostics and linguopersonology.
