The word "signs" in literature is a versatile and multi-layered term, used to denote everything from physical gestures to symbolic indicators of deeper meanings. In some texts, signs are literal signals or gestures—actions such as a captain’s directional motions ([1]) or the subtle nonverbal communications between characters ([2], [3]) that serve as immediate cues in social interactions. In religious and philosophical contexts, “signs” are often miraculous or divinely ordained markers, as seen in biblical passages that speak of wonders and portents, affirming faith and destiny ([4], [5], [6]). Meanwhile, in more secular narratives, signs become tokens or evidences of change, decay, or forthcoming events—whether it’s the physical evidences of illness ([7], [8]), subtle hints in nature that foreshadow impending shifts ([9], [10]), or even abstract symbols that capture emotional or societal states ([11], [12]). Thus, across genres and epochs, the term "signs" operates on multiple levels, simultaneously grounding narratives in tangible reality and elevating them into the realm of symbolic interpretation ([13], [14]).
