oversight

Etymology

It is inherited from Middle English oversight, formed in Middle English from over- and sight,^[2][3][4] after the earlier verb oversee.^[2][5]

Earliest recorded meaning

All-encompassing sight, a rare sense found only before 1400, in Cursor Mundi.^[2] The lasting sense, supervision or charge of something, is first quoted in 1413.^[2] The Middle English Dictionary records it for supervision and custody, and in phrases such as by the oversight of, under the direction of.^[6]

Semantic evolution

The word grew out of oversee, to look over and so to watch over, and its first meanings were watchful care and management.^[2][4] From 1477 the other sense of over took hold, as in overlook: passing over something without seeing it, and by 1531 a mistake made that way, so that the word came to mean both close attention and a lack of it.^[2][3] In American usage the first sense also has a formal political application, the regulatory supervision of government agencies, as in congressional oversight.^[7]
