Bile \Bile\, n. [L. bilis: cf. F. bile.]
   1. (Physiol.) A yellow, or greenish, viscid fluid, usually
      alkaline in reaction, secreted by the liver. It passes
      into the intestines, where it aids in the digestive
      process. Its characteristic constituents are the bile
      salts, and coloring matters.

   2. Bitterness of feeling; choler; anger; ill humor; as, to
      stir one's bile. --Prescott.

   Note: The ancients considered the bile to be the ``humor''
         which caused irascibility.
