The word "convulse" in literature often functions to evoke a sudden, forceful disturbance—whether in the physical body or in abstract systems. Authors use it to describe uncontrollable physical reactions, such as a character's body jerking upright or laughter shaking a face ([1], [2], [3], [4]), while it also vividly illustrates the shockwaves of emotional or political upheaval, shaking families, communities, or even entire nations ([5], [6], [7], [8]). This dual usage not only brings intensity and immediacy to physical sensations but also reinforces the dramatic transformation or disruption of established orders in society.
