upon(prep.)
早在12世纪初,源自古英语 uppan(介词)“在...上面,到...上面,对抗...,靠近...”,由 up(副词)和 on(介词)组成; 可能受到斯堪的纳维亚诸语言的影响,如古诺尔斯语 upp a。
On, Upon. These words are in many uses identical in force, but upon is by origin (up + on) and in use more distinctly expressive of motion to the object from above or from the side. On has the same force, but is so widely used in other ways, and so often expresses mere rest, that it is felt by careful writers to be inadequate to the uses for which upon is preferred. [Century Dictionary, 1895]
On, Upon. 这些词在许多用法上的力量是相同的,但 upon 是由 up 和 on 组成的,更明显地表达了从上方或侧面到对象的运动。 On 具有相同的力量,但由于在其他方面被广泛使用,并且经常仅表示静止,因此被认为对于 upon 所偏爱的用途不足。[世纪词典,1895]
