The quality or state of being able to be described or supported with specific details and evidence.
From circumstantiable + -ity (a suffix forming nouns of quality). Built on circumstantial, derived from circumstance. The suffix -ity converts an adjective quality into a countable state.
This ultra-formal noun appears mainly in legal and academic writing to discuss whether a claim can actually be backed up with concrete details. It's what separates a wild accusation from something that's circumstantiable—provable through circumstances.
