Etymology

It is a Middle English compound of up and on,[2][3][4] formed after Old Norse upp á,[5][6][7] continuing Old English uppon, uppan “on, up to, against”.[2]

Earliest recorded meaning

“Above and touching; upwards so as to be on”: the early 12th century,[2] with the OED's earliest quotations from about 1250.[8]

Semantic evolution

The OED notes that the compound originally expressed elevation as well as contact.[8] The adverb, “on it, on the surface”, is from 1307,[8] and “thereafter”, as in thereupon, from the 14th century.[8] The Century Dictionary observed that upon is by origin more expressive of motion onto an object from above or from the side, but that it is often scarcely more than a synonym of on.[2] Once upon a time and upon my word keep the word in fixed phrases.[5]
