The state of being freed from false beliefs or illusions, often leading to disappointment about someone or something that was once admired.

Disenchantment → It is formed from "dis-" (meaning apart or away) and "enchant" (from Old French *enchanter*, meaning to charm or cast a spell). The word describes the state of being freed from a charm or spell, thus losing enchantment or magic.
Think of being 'freed from' ('dis-') a 'charm' ('enchant') — that's why disenchantment means losing the magic or charm of something.
