Morphology
undemonstrable = demonstrable (transparent) = un + demonstrate + able
Adding the productive negative prefix 'un-' to 'demonstrable' yields a direct negation; 'demonstrable' itself is transparently 'demonstrate' + '-able'.
Etymology
The word undemonstrable is made of the prefix un- meaning 'not' and demonstrable, from demonstrate meaning 'to show'. So, something undemonstrable cannot be 'shown' or proved by evidence.
