I'm trying to recall a specific (and interesting) verb, which I'm 90% sure exists.
The verb means, roughly, to make someone aware of something, to open their eyes. But it's used in a particular way: in the sense of relieving someone of their prior, mistaken views (perhaps by revealing some new evidence, or pointing out something they simply hadn't considered before).
Examples:
"She _______ him of [some notion he held] by pointing out [something]."
"Seeing the reality of how they lived _________ me of any [conservative/socialist/whatever] leanings I might have held."
