Stark \Stark\, adv.
   Wholly; entirely; absolutely; quite; as, stark mind. --Shak.

                                                  --Fuller.

   {Stark naked}, wholly naked; quite bare.

            Strip your sword stark naked.         --Shak.

   Note: According to Professor Skeat, ``stark-naked'' is
         derived from steort-naked, or start-naked, literally
         tail-naked, and hence wholly naked. If this etymology
         be true the preferable form is stark-naked.
