flavor

flavor n.  1. Variety, type, kind.  "DDT commands come in
   two flavors."  "These lights come in two flavors, big red ones
   and small green ones."  See {vanilla}.  2. The attribute that
   causes something to be {flavorful}.  Usually used in the phrase
   "yields additional flavor".  "This convention yields additional
   flavor by allowing one to print text either right-side-up or
   upside-down."  See {vanilla}.  This usage was certainly
   reinforced by the terminology of quantum chromodynamics, in which
   quarks (the constituents of, e.g., protons) come in six flavors
   (up, down, strange, charm, top, bottom) and three colors (red,
   blue, green) -- however, hackish use of `flavor' at MIT predated
   QCD.  3. The term for `class' (in the object-oriented sense) in
   the LISP Machine Flavors system.  Though the Flavors design has
   been superseded (notably by the Common LISP CLOS facility), the
   term `flavor' is still used as a general synonym for `class'
   by some LISP hackers.
