To take away or remove, especially in legal contexts referring to the removal of a bequest or inheritance from a will.
From Latin 'ademptus', past participle of 'adimere' (to take away). The term entered English law and is still used in probate law to describe when a gift in a will is removed or cancelled.
If a grandparent leaves their house to a grandchild in a will but sells it before dying, the gift has been 'adempted'—and this creates family drama in probate courts!
