'wedge' originates from Old English, specifically the word 'wecg', where 'wecg' meant 'a wedge or a piece of wood'.

'wecg' changed from Old English word 'wecg' and eventually became the modern English word 'wedge'.

Initially, it meant 'a piece of wood or metal with a pointed edge', but over time it evolved into its current meaning of 'to force into a narrow space'.
