Why “milse” is a great word
To be merciful to; to show clemency or pardon. From Middle English milsen, milcen, milcien, from Old English miltsian ("to compassionate, pity, show mercy"), from Proto-Germanic *mildisjō ("kindness"), from *mildijaz ("mild"), from Proto-Indo-European *(s)mel- ("to beat, grind"). Unlike "forgive," which implies the surrender of a personal grievance, or "absolve," which suggests a formal release from debt, to *milse* is the deliberate withholding of a blow one has the right to deliver. It is the judge staying the sentence, the victor turning his gaze from the foe, the winter sun granting a thaw—a conscious softening of justice's hard edge, wrought from the ancient understanding that all things are ground fine enough.
