Difference Between Allusion and Illusion

Allusion vs Illusion
 

As allusion and illusion are very similar sounding words in English language that tend to create a problem when spoken in a fast manner, we should try and distinguish the difference between allusion and illusion. As allusion and illusion both seem to sound the same when spoken in a fast manner, then the listener has to grope in the dark or search for the context in which the word was spoken to understand the meaning of the sentence.

The difference lies in the prefixes used with the two words which are an- in allusion and in- in illusion. It is these prefixes that make all the difference in the meanings of these two words.
