Etymology

Derived from Latin illusus (past participle of illudere, "to mock or deceive"), combining il- (variant of in-, "not") and ludere ("to play"). The root lus reflects the idea of "playful trickery," evolving into English to describe things that deceive the senses or mind. The suffix -ive turns it into an adjective, emphasizing the quality of being misleading.
