14世纪晚期, diffusioun,“大量倾泻”,源自古法语 diffusion,直接源自拉丁语 diffusionem(主格 diffusio),“倾泻”,动名词来自 diffundere “散布,倾泻”,由 dis- “分开,向各个方向”(见 dis-)和 fundere “倾泻”(来自 PIE 词根 *gheu- “倾泻”经过鼻化形式)。 “扩散的行为,扩散的状态”是从1590年代开始的; 比喻意义上的“广泛传播,散布”(知识等)是从1750年代开始的。

Middle English diffusioun "outpouring (of speech)," borrowed from Late Latin diffūsiōn-, diffūsiō "pouring out (of liquids), watering of the eyes, abundance" (Latin, "geniality"), from Latin diffud-, variant stem of diffundere "to pour out over a wide surface, spread out, extend" + -tiōn-, -tiō, suffix of verbal action — more at diffuse >entry 2
The first known use of diffusion was in the 15th century
