vt. to free or deprive of illusion or false belief
n. the state of being freed from illusion or false belief
The word "disillusion" combines the prefix "dis-" (meaning "undo" or "reverse") with "illusion" (from Latin illusio, meaning "mockery" or "deception"). The prefix "dis-" negates or reverses the state of being deceived, creating a verb meaning "to free someone from false beliefs." The term emerged in the 17th century, reflecting a shift toward rationalism and skepticism in European thought.
