over: [OE] Etymologically, over denotes ‘more up, upper’. It originated as an Indo-European comparative form derived from the base *upó ‘under’, which gave rise to English up. This became prehistoric Germanic *uberi, which has diversified into German über, Swedish ?fver, and Dutch, Danish, and English over. A derivative of the same base forms the second syllable of English above, while amongst over’s more surprising relatives are eaves and evil. => above, eaves, evil, up
over (prep.)
Old English ofer "beyond, above, upon, in, across, past; on high," from Proto-Germanic *uberi (cognates: Old Saxon obar, Old Frisian over, Old Norse yfir, Old High German ubar, German über, Gothic ufar "over, above"), from PIE *uper (see super-). As an adjective from Old English uffera. As an adverb from late Old English. Sense of "finished" is attested from late 14c. Meaning "recovered from" is from 1929. In radio communication, used to indicate the speaker has finished speaking (1926). Adjective phrase over-the-counter is attested from 1875, originally of stocks and shares.
