Definite and definitive both apply to what is precisely defined or explicitly set forth. Butdefinitive generally refers specifically to a judgment or description that serves as a standard or reference point for others, as inthe definitive decision of the court (which sets forth a final resolution of a judicial matter) orthe definitive biography of Nelson (i.e., the biography that sets the standard against which all other accounts of Nelson`s life must be measured).
Definite 和 definitive 都适用于指被精确限定或清楚地公布出来的东西。 但definitive 通常特指作为对其它事物的标准或参照点的判断或描述， 如在法庭的最终判决 中（为案件提出了决定性决议的最终判决）， 或纳尔逊的可靠的传记 （指一种传记，为有关纳尔逊的生活所作的其它叙述提出参照标准）
