The word "spasmodic" is employed to evoke sensations of erratic, sudden, and often involuntary action, whether describing physical movements, intermittent efforts, or even bursts of speech. In literature, the term is used to paint vivid images of bodily convulsions, such as the abrupt muscle contractions in a character's neck or limbs ([1], [2], [3]), as well as to illustrate the irregular and unpredictable flow of emotions or attention ([4], [5]). Its application ranges from portraying clinical or medical conditions—like convulsive asthma or tremors ([6], [7])—to enriching narrative descriptions of dramatic outbursts or fleeting, disrupted states ([8], [9], [10]). Overall, "spasmodic" functions as a versatile descriptor, capturing both the physical and metaphorical suddenness and irregularity inherent in human actions and conditions.
