Della Crusca \Del"la Crus"ca\
   A shortened form of Accademia della Crusca, an academy in
   Florence, Italy, founded in the 16th century, especially for
   conserving the purity of the Italian language.

   Note: The Accademia della Crusca (literally, academy of the
         bran or chaff) was so called in allusion to its chief
         object of bolting or purifying the national language.
