The text analyzes the philosophical term "pobyt," introduced by Jan Patočka as a translation of Heidegger's "Dasein." The author argues that the Czech term is conceptually deeper than the German original, as it moves beyond simple spatial localization to emphasize the temporal character and limited duration of existence. Within the proposed framework of FYSIS – body – subject, "pobyt" is defined by birth, organized duration, and death, rather than mere accidental occurrence. While the body serves and is subordinate to "pobyt," the essence of staying or residing lies in the active, effective presence of the subject. This subject is characterized as a fundamental "non-being" leaning into the future. Ultimately, "pobyt" is presented not as a static state, but as a dynamic activity and an ongoing "presence" that constitutes the core of human being. The analysis highlights how language shapes ontological understanding, favoring "pobyt" for its ability to capture the intersection of life, body, and subjectivity.
