Did you see how she handled that criticism?

Yeah, she seemed to brush it off imperviously.

Synonyms & Antonyms

Root Explanation

Imperviously → It is formed from "im-" (meaning not) and "pervius" (from Latin, meaning passable or penetrable) and the suffix "-ly" (meaning in a manner). The word "imperviously" means in a manner that is not penetrable or not allowing passage.

Memory Tip

Think of 'not' ('im-') allowing something to 'pass through' ('pervius') — that's why imperviously means something that does not allow anything to pass.
