•  The withdrawing or withholding from a person of some right to which he is entitled by law.  [1913 Webster]

  " Thus the subtraction of conjugal rights is when either the husband or wife withdraws from the other and lives separate without sufficient reason. The subtraction of a legacy is the withholding or detailing of it from the legatee by the executor. In like manner, the withholding of any service, rent, duty, or custom, is a subtraction, for which the law gives a remedy."  Blackstone.  [1913 Webster]
