oversee (v.)

Old English oferseon "to look down upon, keep watch over, survey, observe;" see over- + see (v.). Meaning "to supervise to superintend" is attested from mid-15c. The verb lacks the double sense of similar overlook, but it sometimes had it and this survives in the noun form oversight.  Compare German übersehen, Dutch overzien. Related: Oversaw; overseen.
