what is a crisis

A crisis (from the Greek κρίσις - krisis; plural: “crises”; adjectival form: “critical”) is any event that is going (or is expected) to lead to an unstable and dangerous situation affecting an individual, group, community, or whole society.

Crises are deemed to be negative changes in the security, economic, political, societal, or environmental affairs, especially when they occur abruptly, with little or no warning. More loosely, it is a term meaning “a testing time” or an “emergency event”.
