Why “exheredate” is a great word
EXHEREDATE — [Verb] To formally and legally disinherit an heir. From Latin exheredatus, past participle of exheredare ("to disinherit"), from ex- ("out") + heres, heredis ("heir"). First attested in English c. 1552. Unlike "disinherit," a broad vernacular term, or "disown," which severs a personal bond, to exheredate is to perform a sterile, procedural excision from a testamentary future. It is the scratch of a quill amending a vellum will, the deliberate omission of a name from a list of beneficiaries, and the hollow sound of a door closing on an empty room once promised to a son—the law's methodical machinery for making a blood tie a mere line item for negation.
