What is come down? How to use in English

The origin of the phrase "come down" can be traced back to the late 1800s. At that time, "come down" was used to describe a drop in stock prices or the value of goods in the market. However, the phrase later acquired a different meaning in the early 1900s. It came to be used in reference to a state of mind or body, where someone experiences a drop in energy or feelings of exhaustion. This could be as a result of intoxication, illness, or a prolonged period of activity. The phrase "come down" also has geographical variations. In the United States, "come down" often refers to the use of drugs or a hangover from a party the previous night. In the United Kingdom, it is more likely to refer to a drop in mood or emotional state. The flexibility and versatility of the phrase have led to its use in various contexts, such as meteorology or weather forecasts, where it describes a drop in atmospheric pressure and potentially snowfall or rain. In summary, the origin of the phrase "come down" began as a reference to a drop in stock prices or value, but has since evolved to refer to a drop in energy, mood, or weather conditions.
