How can you compare and contrast puns and malapropism?

Answer 1

A pun is a word play that exploits multiple meanings of words for an intentional humorous or rhetorical effect,

A malapropism is the use of an incorrect word in place of a word with a similar sound. The result is nonsensical and often humorous.

The difference between puns and malapropism is that a pun uses a correct expression that alludes to another expression that could also be correct, but is humorous. A malapropism uses an incorrect expression that alludes to another, often correct statement.
