This article will throw light on allusion and illusion as nouns, their origins, usage and examples in real life.

Origin:

The word allusion originated in mid-16th century (denoting a pun, metaphor, or parable): from French, or from late Latin allusio(n- ), from the verb alludere meaning allude. The word illusion originated from Middle English (in the sense ‘deceiving, deception’): via Old French from Latin illusio(n- ), from illudere ‘to mock’, from in- ‘against’ + ludere ‘play’.

Allusion as noun:

Allusion is used in English language as a noun where it means an expression designed to call something to mind without mentioning it explicitly; an indirect or passing reference.

Allusion or illusion:

An allusion is a reference, direct or implied, to something or someone. Allusions are often found in books, songs, TV shows, and movies. For instance, the title of Aldous Huxley’s classic novel Brave New World is allusion to a work by William Shakespeare. An illusion, on the other hand, is something that deceives the mind or senses by creating a false impression of reality. Illusions are often (though not always) related to visual perception, as in optical illusion. A mirage, such as the phenomenon of perceiving a sea of water in a desert, is a type of illusion. To keep them straight, try associating the “i” in illusion with an eye, relating the term to optical illusions.
