Morphology

unsustainable = sustainable (transparent) = un + sustain + able

The prefix 'un-' clearly negates the meaning of 'sustainable'.

Etymology

Unsustainable comes from un- 'not' and sustain 'to hold up' or 'support'. So if something is unsustainable, it cannot be 'held up' or 'kept going' for a long time, like a chair that cannot hold you or a plan that will fall.
