I heard that her imperviousness to criticism is quite impressive.

Root Explanation

Imperviousness → It is formed from "im-" (meaning not) and "pervius" (from Latin, meaning passable or allowing passage) and the suffix "-ness" (meaning the state of being). The word "imperviousness" means the state of being not able to be passed through or penetrated.

Memory Tip

Think of 'not' ('im-') allowing something to 'pass' ('pervius') — that's why imperviousness means the state of being unable to be penetrated.
