Morphology

conclusive = conclude (transparent) = conclude + ive

Derived from the verb 'conclude' with the adjectival suffix '-ive'; the meaning 'serving to conclude or decisive' is readily predictable from the base.

Etymology

The word conclusive comes from Latin parts con- 'together' and claudere 'to shut', the same idea behind the English words close and conclude. So, something conclusive 'closes' a question or argument and ends doubt.
