The word "tractable" has been employed in literature to capture a sense of pliability and readiness to be influenced, whether referring to people, animals, or even inanimate materials. In some works, characters are depicted as compliant or easy to manage—a trait seen in a faithful husband or a gentle wanderer ([1], [2], [3]). At other times, the word describes animals, such as a mare that is both obedient and rideable ([4], [5]). Its metaphorical use extends to the physical world, with ancient texts noting the inherent malleability of copper compared to iron ([6]). Meanwhile, authors sometimes contrast tractability with stubborn defiance, as with individuals unwilling to be controlled ([7], [8]), or even use it to mark the ease with which groups can be directed or subdued ([9], [10]). This breadth of application underscores the term’s versatility in literature across different eras and genres.
