Question

A sentence that uses the words impudence and derision

Answer 1

Impudence is a very annoying trait of some rude people - such behavior is a pure derision to the peace and serenity of those who have to face it.

Something like this, it just came to my mind :)

Answer 2

Impudence is a kind of shamelessness or insolence. It also refers to a lack of modesty. On the other hand, derision refers to a kind of mockery, ridicule or contempt.

An example of a sentence could be:

"The impudent couple received the performer with derision."
