Surface Forms
Morphology
unsubstantiatable = substantiable (transparent) = un + substantiat + able
The adjective is formed by standard negation (un-) applied to 'substantiable' (substantiate + -able), so the meaning 'not able to be supported/proven' is directly compositional.
Etymology
Unsubstantiatable is built from un- 'not', the root substance meaning 'stuff' or 'evidence', and -able 'able to'. So something unsubstantiatable is 'not' able to be given 'substance', which explains why it means it cannot be proven or supported with evidence.
