The term “flexible” in literature is employed both as a descriptor of physical dexterity and as a metaphor for adaptability and resilience. Authors use it to capture the fluidity and dynamism of bodily movement—for instance, a high, flexible neck that brings a creature vividly to life [1] or a voice described as “smooth and true, flexible and full” [2]. At the same time, it extends to the abstract realm, suggesting the capacity to yield, adjust, and transform, whether in reference to a character’s temperament, the pliability of intellectual constructs [3], or even the malleable structure of societal systems [4]. In other contexts, “flexible” characterizes the material properties of objects like cloth [5] or technical components [6], reinforcing the idea that versatility and ease of adaptation are prized qualities in both animate and inanimate forms.
