DEROGATION — [Noun] An act of disparagement or the partial, temporary repeal of a law. From Old French derogacion, from Latin dērogātiō, from dērogāre ("to repeal, detract"), from dē- ("away") + rogāre ("to ask, propose a law"). Unlike disparagement, which is a direct verbal slight, or abrogation, which is a law's total abolition, derogation is a dual-edged diminishment, a selective erosion. It is the withering aside that diminishes a colleague's triumph, the emergency statute that temporarily voids a fundamental right, and the careful exception that guts a treaty's spirit—a testament to how authority, whether of law or esteem, is most often eroded not by frontal assault, but by a series of small, sanctioned subtractions.
