The English word tycoon comes from Japanese. It was borrowed from taikun, a term meaning great lord or great prince. In the 1800s, English speakers used it for a powerful ruler in Japan.
Over time, the meaning shifted in English. Instead of referring to a Japanese political figure, tycoon came to mean a person with great power and wealth in business or industry. That is the sense most people know today.
For example, someone might speak of a railroad tycoon, a media tycoon, or a steel tycoon. In each case, the word suggests not just money, but also influence and control.
This is a good example of how borrowed words can change after entering English. The source word had a specific political meaning in Japanese, but English gave it a broader meaning tied to business success and status.
- Original sense: a great lord or high ruler in Japan
- Modern English sense: a very wealthy and powerful business leader
