   Usage: {Racy}, {Spicy}. Racy refers primarily to that
          peculiar flavor which certain wines are supposed to
          derive from the soil in which the grapes were grown;
          and hence we call a style or production racy when it
          ``smacks of the soil,'' or has an uncommon degree of
          natural freshness and distinctiveness of thought and
          language. Spicy, when applied, has reference to a
          spirit and pungency added by art, seasoning the matter
          like a condiment. It does not, like racy, suggest
          native peculiarity. A spicy article in a magazine; a
          spicy retort. Racy in conversation; a racy remark.

                Rich, racy verses, in which we The soil from
                which they come, taste, smell, and see.
                                                  --Cowley.
