Etymology

Origin of crisis

First recorded in 1375–1425; late Middle English, from Latin crisis “(medical) crisis,” from Greek krísis “decision, interpretation,” equivalent to kri- variant stem of krīnein “to decide, separate, judge” + -sis -sis

Explanation

A crisis is a difficult or dangerous time in which a solution is needed — and quickly. For example, the crisis caused by a natural disaster might inspire you and your friends to make a donation. The noun crisis comes from the Latinized form of the Greek word krisis, meaning "turning point in a disease." At such a moment, the person with the disease could get better or worse: it's a critical moment. Think of a celebrity whose recent antics generate headlines like "Rock Star in Crisis" — that person needs help that may or may not be sought. At the moment of crisis, things are unstable and maybe even dangerous.
