The act of annulling; the process of canceling, voiding, or declaring something null and void.
From Late Latin 'annullatio,' combining 'annullare' (to annul) with '-tion' (denoting action). This is essentially a synonym for 'annulment' but is rarely used in modern English.
Medieval lawyers used 'annullation' to describe papal annulments—they literally claimed a marriage was 'nothing'—a legal fiction so powerful it could undo years of a person's life with official paperwork.
