The word "fluctuation" appears in literature as a versatile term, used to capture the idea of variability in various contexts. In some works, such as in [1] and [2], it describes measurable changes—a slight fluctuation in price or temperature—that underscore practical concerns in everyday life and commerce. In contrast, authors like Joyce in [3] employ the term more abstractly to explore the shifting nature of emotional or sensory experiences, suggesting that even attraction can vary in intensity. Meanwhile, figures like Irving in [4] and Santayana in [5] use "fluctuation" metaphorically, applying it to language and human nature to express the intrinsic instability in our thoughts and societal constructs. The term also finds its place in historical and economic commentary, as seen in [6] and [7] where the fluctuation of credit underpins financial uncertainty, and in [8] and [9] where it captures the cyclical change of natural phenomena. This diverse employment of "fluctuation" across genres and subjects emphasizes its rich capacity to convey both tangible and ephemeral shifts within the world.
