Synonym discussion

Sense: noun/1

For the mistake sense, oversight usually points to a small problem caused by not noticing something or forgetting a step. Mistake is the broad everyday word and can describe almost any wrong action. Error is a little more formal and is common for numbers, facts, or computer results. Omission focuses on something that was left out, such as a missing name or page. Slip is informal and often suggests a brief moment of carelessness. Use oversight when you want to show that the problem was accidental and often understandable. Compare: Leaving one page out of the form was an oversight. A wrong total in the report was an error.

Etymology

Old EnglishMiddle EnglishEnglish

Oversight has been in English since the 1400s. It was formed from over and sight, and it first referred to careful watching or supervision. Soon after, it also developed the opposite idea of missing something while passing over it, which led to the modern 'mistake' sense. That history explains why one word can mean both supervision and an accidental failure to notice.
