Allusion:
* Definition: An indirect or passing reference to a person, place, thing, or event, often from literature, history, or mythology.
* Example: "The speaker's words were an *allusion* to Shakespeare's Hamlet." (The speaker isn't directly quoting Hamlet, but referencing something from the play)
Illusion:
* Definition: A false perception or belief; a misleading appearance.
* Example: "The magician used smoke and mirrors to create an *illusion* of a disappearing act." (The magician didn't actually make anything vanish, they just tricked the audience into thinking so)
Key Differences:
* Allusion: Refers to something else, usually indirectly.
* Illusion: Creates a false impression or perception.
Here's a simple way to remember:
* Allusion has two "l"s like "literature," which is often the source of an allusion.
* Illusion has one "l" like "false," which is a key element of an illusion.
