(invalidate)
make invalid
Etymology
'invalidate' originates from Latin, specifically the Medieval Latin word 'invalidare', where 'in-' meant 'not' and 'validus' meant 'strong' or 'effective'.
'invalidate' changed from the Medieval Latin verb 'invalidare' and entered English usage (via learned/formal borrowing) in the modern period as 'invalidate'.
Initially it meant 'to weaken or make ineffective', but over time it evolved into its current meaning of 'to make legally or logically not valid'.
