This text examines the semantic connection between the verb "to be" and the concepts of commitment or duty across various languages, including Czech, Latin, and Ancient Greek. Drawing on Aristotle's assertion that "it is" for the philosopher to theorize about all things, the author demonstrates that the verb "to be" often carries an inherent normative weight. This linguistic structure suggests that existence cannot be easily reduced to mere facticity, neutrality, or a simple occurrence of things. Instead, in many contexts, the word "is" can and must be interpreted as an expression of necessity, a task, or a moral obligation. The reflection argues that language itself resists the neutralization of being into a mere set of data. By expanding the meaning of "is" into the realm of "it is necessary" or "it is required," ontology becomes inextricably linked with responsibility. This phenomenon reveals a profound philosophical layer of human understanding, where existence is not a passive state but an active calling toward a specific purpose and the fulfillment of a duty.
