Morphology

unsustained = sustained (transparent) = un + sustain + ed

The prefix 'un-' clearly negates the adjective 'sustained', making the meaning directly derivable.

Etymology

Unsustained comes from un- ('not') and sustain ('to hold up' or 'keep going'). So unsustained describes something that was not kept up or continued.
