the action or process of freeing someone from a false belief or mistaken idea; disillusionment or correction of misconception.
From 'disabuse' (prefix 'dis-' + 'abusive' or 'abuse,' meaning to use incorrectly) plus the noun suffix '-al,' which creates abstract nouns from verbs. The prefix 'dis-' reverses the sense of 'abuse' to mean correcting misuse.
Disabusal is a wonderfully formal word that means 'getting someone to stop believing something wrong'—it's the kind of word that shows up in 18th-century philosophy but sounds pretentious today, making it a perfect example of vocabulary that ages out of everyday use!
