Etymology
The word 'invalidation' is built upon the Latin verb valere, meaning "to be strong, to be of worth". From this, the adjective validus (strong, effective) was derived. The prefix in- negates this core, creating the sense of "not strong" or "not effective". The suffix -ation then transforms this concept into a noun denoting the action or state of rendering something without force or legal efficacy. Thus, the literal journey from "strength" to "the act of removing strength" provides a clear logical path to the modern abstract meanings of nullification or disproval.
