'overrule' originates from Middle English, specifically the word 'overrulen,' where 'over-' meant 'above' and 'rulen' meant 'to govern or control.'

'overrulen' transformed into the modern English word 'overrule' through Middle English.

Initially, it meant 'to govern or control above others,' but over time it evolved into its current meaning of 'to reject or disallow by authority.'
