Etymology
该词直接源自莎士比亚戏剧《暴风雨》（1610年）中 Ariel 的歌词：“Full fathom five thy father lies; / Of his bones are coral made; / Those are pearls that were his eyes: / Nothing of him that doth fade, / But doth suffer a sea-change / Into something rich and strange.” 这里的“sea-change”原指海水对物体的彻底、神奇转化（如骸骨变珊瑚、眼睛变珍珠）。现代用法保留了“根本性转变”的核心意象，但拓宽到任何深刻、常指向积极或根本的质变，强调变化之彻底与自然，仿佛经海洋之力重塑。
