Did You Know?

When English speakers first borrowed the Greek word catastrophe in the 1500s, they used it for the conclusion or final event of a dramatic work, especially of a tragedy. By the early 1600s, "catastrophe" was being used more generally of any generally unhappy conclusion or disastrous or ruinous end. By the 18th century, "catastrophe" had come 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.
