Morphology

decisive = decide (transparent) = decis + ive

The sense 'clear or unmistakable' extends straightforwardly from the notion of producing a decisive (decision-making) outcome; morphology remains regular.

Etymology

Decisive comes from the Latin parts de- ('off') and caedere ('to cut'), like a clean cut that leaves nothing extra. So when something is decisive it is clear and leaves no doubt.
