He commented that her house was no palace
Step-by-step explanation:
A litote is an understatement that expresses the affirmative by saying the negative of the contrary. The other statements are all just statements, they do not give any indication of a deeper level of meaning. Another example of a litote is: That wasn't the messiest house I've ever seen. In this statement, the house is being described as messy by saying that it is not.
