Did you know?

When English speakers first borrowed the Greek word katastrophē (from katastrephein, meaning "to overturn") as catastrophe in the 1500s, they used it for the conclusion or final event of a dramatic work, especially of a tragedy. In time, catastrophe came to be used more generally of any unhappy conclusion, or disastrous or ruinous end. By the mid-18th century, it was being used to denote truly devastating events, such as earthquakes and volcanic eruptions. Finally, it came to be applied to things that are only figuratively catastrophic—burnt dinners, lost luggage, really bad movies, etc.
