Morphology

indemonstrable = demonstrable (transparent) = in + demonstr + able

The negative prefix 'in-' attaches regularly to 'demonstrable' and yields the straightforward meaning 'not demonstrable'.

Etymology

Indemonstrable is made of the prefix in- ('not') and demonstrable, from demonstrate meaning 'to show' or 'to prove', so it describes something 'not able to be shown or proved'.
