Morphology

inconclusive = conclusive (semi-transparent) = in + conclude + ive

For learners who know 'conclusive', adding 'in-' clearly gives the meaning 'not conclusive'.

Etymology

The word inconclusive is made of in- ('not') and the same root as conclude and conclusion, which mean 'close' or 'finish'. So, something inconclusive does not 'close' the question and leaves doubt instead of a clear decision.
