forbivisse
noun
The weight of possessing knowledge that feels forbidden, a secret too painful and dangerous to tell; speaking it aloud may lead to irrevocable consequences, even death. This burden is a heavy chain, keeping one trapped in silence and fear.
From Latin 'forbidere' (to forbid) + 'visse' from 'visus' (sight), indicating something seen but not to be disclosed. Pronounced 'for-BIH-viss'.
