A mistake or error that happens because something was not noticed or taken care of. It can also mean the act of overseeing or managing something carefully.
The project was delayed due to an oversight in the planning process.
Oversight → It is formed from "over-" (meaning above or beyond) and "sight" (from Old English "sīht", meaning vision or seeing). The word "oversight" refers to the act of overseeing or supervising something, often implying a level of authority or responsibility that is above the usual level of observation.
Think of someone having a view or 'sight' that is 'above' ('over-') the usual level, which helps you remember that 'oversight' means to supervise or oversee.
