History and etymology of omission

The noun 'omission' can be traced back to the Latin word 'omissio,' which is derived from the verb 'omittere.' In Latin, 'omittere' is a combination of 'ob' (meaning 'away') and 'mittere' (meaning 'to send' or 'to let go'). This etymology reflects the notion of something being left out or neglected intentionally or unintentionally. When 'omittere' evolved into 'omissio' and later into 'omission' in English, it retained the sense of an act of leaving something out or failing to include it, particularly when it should have been mentioned or included. Thus, the etymology of 'omission' emphasizes the action of omitting or excluding, highlighting its linguistic roots in the Latin language.
