USAGE NOTE   Definite and definitive both apply to what is precisely defined or explicitly set forth. But definitive most often refers specifically to a judgment or description that serves as a standard or reference point for others, as in the definitive decision of the court (which sets forth a final resolution of a judicial matter) or the definitive biography of Nelson (that is, the biography that sets the standard against which all other accounts of Nelson's life must be measured).
