Etymology

Origin of impassive

First recorded in 1660–70; im- 2 + passive

Explanation

Someone who doesn't seem to react — who is always "taking a pass" in the conversation of life can be described as impassive. Impassive is tricky, as it sounds it should be the opposite of passive. It's not, though. The fact is you can be passive and impassive at the same time. When a passive person gets passed over for a promotion at work, their face might remain impassive upon hearing the news.
