Etymology
'invalidation' originates from Latin, specifically the Medieval Latin word 'invalidare', where the prefix 'in-' meant 'not' and the root 'validus' meant 'strong' or 'worthy'.
'invalidation' changed from the Medieval Latin 'invalidare' (and via Old/Middle French 'invalider') and eventually became the modern English noun 'invalidation' derived from the verb 'invalidate'.
Initially, it meant 'to make not valid' (to deprive of validity), and over time it has retained that core meaning while gaining specialized senses (e.g., computing cache invalidation).
