This text examines the historical and linguistic development of the term "subject" and its relationship with the term "object." The author traces the etymological roots of these terms in Latin, where confusion existed between the meanings "to lie under" and "to throw under." The original Aristotelian concept understood the subject as an unchanging foundation beneath surface changes. Over time, particularly with the onset of the modern era, the emphasis shifted toward human activity and the capacity to initiate change. The text analyzes the Czech equivalents "podmět" and "předmět," which refer to the act of "casting," and compares them with German developments. A fundamental transformation of the meaning of the subject toward internal activity and individuality was brought about by German Romanticism and thinkers such as Kant, Hegel, and especially Kierkegaard. While the meaning of "subject" is strictly defined in modern German, languages like English and French retain broader contexts linked to the original meanings. Overall, the study illustrates how a passive carrier evolved into an active agent.
