Writers wield the term "frigid" to evoke not only literal coldness but also an emotional or social chill that permeates behavior and dialogue. In one vein, it depicts physical barrenness or the unyielding severity of nature, as when characters traverse or are ruled by harsh climates ([1]) or when weather itself is described as biting cold ([2]). In another, it captures a detached, impassive demeanor—a frigid expression, tone, or reply that suggests a lack of warmth or intimacy, whether in the scoffing retort of a count ([3]) or the cool, calculated intellect of a character ([4]). The word also conveys a metaphorical rigidity, as in frigid jealousy ([5]) or a statement delivered in frigid tones ([6]), underscoring an emotional inhospitality that serves to develop character or set the mood. Such usage—ranging from the frigid majesty of kings to the stoic reserve of everyday interactions ([7], [8], [9])—demonstrates its versatility in enriching literary atmospheres and deepening character portrayal.
