In literature, the term "troubling" serves as a versatile marker of both physical disturbance and inner unrest. At times it reflects a polite apology or an imposition of one's concerns on another, as seen when characters say "excuse me for troubling you" ([1], [2], [3]). In other contexts, it conveys deep-seated emotional or existential agitation—for instance, a secret sorrow that weighs on the heart ([4], [5], [6]). The word also describes disruptions on a broader social or political scale, unsettling traditional norms and expectations ([7]), while at other moments it creates a longing for a peaceful haven where such disturbances cease ([8], [9]). Thus, "troubling" is employed to evoke a spectrum of feelings from gentle regret to profound anxiety across diverse literary canvases.
