In literature, "decline" serves a multitude of roles, reflecting both tangible and abstract processes. In historical narratives, authors describe the inevitable deterioration of once-mighty institutions and civilizations, as seen in the portrayal of the fall of Rome and the waning influence of empires ([1], [2], [3]). The term also captures a natural transition, marking the fading of daylight or the gradual diminishment of mental acuity ([4], [5], [6]). At times, it functions as a marker of deliberate refusal, where characters politely or firmly reject propositions or invitations ([7], [8], [9], [10], [11]). Furthermore, religious and moral texts invoke "decline" as a call to avoid evil and maintain virtue ([12], [13], [14], [15]). This versatile word thus delineates both a physical downfall and a conscious decision to abstain, enriching its significance across genres and eras.
