Morphology

definitive = definite (transparent) = definite + ive

The adjective is directly formed from 'definite' + '-ive', and the sense 'final/clear' is a straightforward adjectival extension.

Etymology

The word definitive comes from the Latin verb definire, made from de- 'completely' and finis 'end'. To 'set the end' is to make something final and clear, so definitive describes an answer or decision that is final and leaves no doubt.
