\Self`-suf*fi"cient\, a.
1. Sufficient for one's self without external aid or
   co["o]peration.
         Neglect of friends can never be proved rational till
         we prove the person using it omnipotent and
         self-sufficient, and such as can never need any
         mortal assistance.                    --South.
2. Having an overweening confidence in one's own abilities or
   worth; hence, haughty; overbearing. ``A rash and
   self-sufficient manner.'' --I. Watts.
