The term gratis has long held a versatile place in literature, consistently evoking the idea of something provided without charge. Its usage spans a wide range of contexts, from humorous inventory in Mark Twain’s depiction of ubiquitous miller-guns [1] to the sober political and social commentaries exemplified by Thomas Jefferson’s admission of offering advice gratis [2]. Authors such as Dostoyevsky [3, 4] and Nietzsche [5, 6] use the word to underline nuances of human behavior and morality, while classical sources like Montaigne’s essays [7, 8] and Augustine’s writings [9] remind us of its deep-rooted Latin origins. Even in pedagogical texts and translations—as seen in Spanish and French readers [10, 11, 12]—gratis is employed to capture the timeless notion of gratuitous benefit, linking works across centuries and genres through the simple, enduring concept of “for nothing.”
