A combination of the English adverb there and the English adverb and preposition upon. The adverb there comes through Middle English from the Anglo-Saxon adverb thaer of the same meaning, which is akin to thar, ther, and dar in other Germanic languages. Upon is a combination of two English adverbs/prepositions, up from the Anglo-Saxon up/uppe and on from the Anglo-Saxon an/on, all of the same meanings. Up is related to other Germanic adverbs/prepositions like Old Norse upp, Dutch op, and German auf, and on is related to the German adverb/preposition an (on) and the Greek adverb/preposition ana (on, upon, up, up to).
