Simplified etymology

Illusion came through Old French from Latin illudere, meaning “mock, ridicule, or make sport of,” formed from in- “against” and ludere “play.” Its earliest English sense was “deception” or “an attempt to fool”; the now common sense “false idea or belief” arose in the late 18th century.

Etymology

From Old French illusion, from Latin illūsiō, from illūdere, from in- (“at, upon”) + lūdere (“to play, mock, trick”). Displaced native Old English dwimmer.
