definite - correct spelling
Note: The adjectives definite and definitive both describe something precisely defined or explicitly set forth. The word definitive, however, refers to something serving as a standard. The definitive decision of the court is a final resolution of a judicial matter. Or the definitive biography of Ronald Reagan is the biography that sets the standard against which all other accounts of President Reagan’s life must be measured.
