The word "lethal" in literature functions both as a descriptor of tangible, deadly danger and as a metaphor for profound, often psychological, impact. It is frequently used to denote precise, quantifiable threats—such as doses of toxins, poisons, or radiation that are fatally effective [1][2][3]. At the same time, the term vividly characterizes settings and characters by imbuing them with an air of inevitable doom, as seen in the portrayal of ominous locales like the Lethal Chamber [4][5][6] or in moments where a single glance carries a fatal promise [7]. Additionally, lethal is not confined solely to the physical realm; it extends metaphorically to describe attributes like a mesmerizing beauty or an overpowering influence that can destroy from within [8][9]. In each usage, lethal sharpens the narrative, accentuating the fine line in which threat and destiny are often intertwined.
