Linguistic Origin & Historical Etymology

The term 'invalidation' is derived from the prefix 'in-' meaning 'not' and the root 'valid', which comes from the Latin 'validus', meaning 'strong' or 'powerful'. The suffix '-ation' indicates the action or process, thus evolving to denote the act of rendering something invalid or null.
