Malapropism
by Adam Huddleston
Here’s another quick literary term to add to your repertoire: malapropism. It is defined as the use of an incorrect word (with a similar sound) for a correct one.
Why would you do this?
It can be used to show that the speaker is confused, upset, or otherwise impaired. It is important to understand that in order to be effective, the two words must be similar in sound or structure.
For example, in “Much Ado About Nothing” a character states: “Our watch, sir, have indeed comprehended two auspicious persons.” In this case, the speaker substituted comprehended for apprehended.
I hope this helps in your writing!
