Morphology

corroboratory = corroborate (transparent) = corroborate + ory

The adjective form is clearly derived from the verb 'corroborate' with the suffix '-ory' indicating a function or relation.

Etymology

Corroboratory comes from corroborate, which is built on the old Latin root robur meaning 'strength' and is the same idea behind the word robust. So corroboratory evidence 'strengthens' or supports a claim, like an oak beam that helps hold a roof in place, and it helps us trust the original report.
