The word "extra" appears across literary works with a rich variety of functions. It sometimes describes an added quantity, as when it qualifies an abundance of utensils or specifies additional expenses in a bill [1][2][3]. At other times, it amplifies qualities or actions, suggesting an augmented strength in a political setting or a heightened effort in a personal endeavor [4][5][6]. The term also frequently refines descriptive details—be it in indicating an unusual physical trait, like an extra shape in clothing, or stressing an extraordinary condition, as with extra-territorial rights or an extra dose of goodwill [7][8][9]. In these ways, "extra" is not only a marker of numerical surplus but also a nuanced modifier that intensifies the narrative, underscoring both mundane and profound variations in everyday life.
