The word "fluctuating" in literature often serves to evoke a sense of instability or continuous change, whether it describes the dynamics of nature, society, or the inner workings of the human heart. It is used to portray the shifting and often unpredictable qualities of physical phenomena—as seen in references to the "fluctuating waves" of social life [1] or the "fluctuating glow" on the horizon [2]—as well as the variability in economic conditions [3] and human emotions, where affections or moods may be "continually fluctuating" [4]. In historical and philosophical works, the term illustrates the transitory balance between forces or the uncertain course of events, suggesting that change is the only constant [5]. Across genres, "fluctuating" imbues descriptions with a dynamic quality that underscores the mutable nature of both the external world and internal states.
