Misimpression → It is formed from "mis-" (meaning wrong or bad) and "impression" (from Latin "imprimere", meaning to press into or onto). The word refers to a wrong or bad impression made on someone.
Think of 'mis-' meaning wrong and 'impression' as something pressed onto your mind — that's why misimpression means a wrong impression.
