A more thorough explanation:

A tradename is a name, symbol, or style that a company uses to identify itself. It is different from a product or service name. A tradename helps a business establish a good reputation and distinguishes it from other businesses.

For example, Coca-Cola is a well-known tradename. It identifies the company that produces the popular soft drink. Another example is Nike, which is a tradename for a company that makes athletic shoes and apparel.

Trademarks can also become tradenames if they acquire a secondary meaning. This means that the trademark becomes so well-known that people associate it with the company that produces the product or service. For example, Kleenex is a trademark for facial tissues, but it has become a commonly used tradename for any brand of facial tissue.

Overall, a tradename is an important part of a business's identity and helps establish its reputation.
