“与肌肉运动相关的”,这个词最早出现在1841年,源自希腊语 kinētikos,意为“移动的,致动的”。它又来自 kinētos,意思是“被移动的”,是动词 kinein(意为“移动”)的形容词形式,追溯到原始印欧语词根 *keie-,意为“使……运动”。
Buster Keaton's subject was kinetic man, a being he approached with the almost metaphysical awe we reserve for a Doppelgänger. This being was, eerily, himself, played by himself, then later in a projection room, watched by himself: an experience never possible to any generation of actors in the previous history of the world. [Hugh Kenner, "The Counterfeiters," 1968]
巴斯特·基顿的作品主题是“动人”,他以几乎是形而上学的敬畏来接近这个主题,就像我们对双胞胎灵魂的敬畏一样。这个“动人”在某种程度上就是他自己,由他自己扮演;而后来在放映室里,他又亲自观看了这一切:这是历史上任何一代演员都无法体验的奇妙经历。[休·肯纳,《伪币制造者》,1968年]
从1855年起,这个词也用来表示“引起运动”。相关词汇包括 Kinetical(动的)和 kinetically(动力学地)。
