nullity

This term carries a heavy sense of absolute negation, often appearing in legal contexts to describe a contract or marriage that is treated as if it never existed. It differs from "invalidity" by implying a total lack of legal effect from the start, rather than a flaw that might be corrected. When applied to people or ideas, the word evokes a feeling of invisibility or total irrelevance. It describes a state of being stripped of power, influence, or value, rendering the subject a non-entity in a social or professional hierarchy.
