Etymology

Origin of impression

First recorded in 1325–75; Middle English impressio(u)n, from Latin impressiōn-, stem of impressiō; equivalent to impress ¹ + -ion

Explanation

An impression is an imprint, either in one’s mind or on an object. To make a good impression on your friend's parents, don't let your muddy boots leave impressions on their perfect white kitchen floor. The noun impression comes from the Latin word imprimere, which means “press into or upon,” or “stamp.” When you press a coin into a piece of modeling clay there will be an impression, or likeness, of its design in the clay. Another kind of impression is a performance in which you act, talk, move and even attempt to look like another person, like the impression of your teacher that got you into trouble when he saw you.
