Definition: An illusion is any magical effect that to the spectator looks impossible, but is accomplished through real-world means. Illusion is often applied to the large stage magic tricks-the kinds with boxes where people are made to disappear, sawed in half, levitated and more.
A person who performs magic is an illusionist. However, the term is mostly applied to performers who present big stage tricks.
Examples: The magician performed the sawing-in-half illusion.
