overturning

The word 'overturning' is built upon the Old English verb 'turnian', meaning to rotate on an axis, which itself has Proto-Germanic origins. The prefix 'over', from Old English 'ofer', adds a sense of reversal, inversion, or moving something from its proper position to an opposite one. The combination 'overturn' literally means to turn something over, a physical action. The addition of the '-ing' suffix nominalizes this action, creating a term that can describe both the concrete act of capsizing and the abstract legal act of reversing a precedent, where the established order is metaphorically turned upside down.
