Final answer:
A trademark is a device or word that identifies the origin of a product and is used to differentiate it from other products.
Step-by-step explanation:
A device or word that identifies the origin of the product, the manufacturer details, etc., is known as a trademark.
A trademark is an identifying symbol or name for a particular good, like Chiquita bananas, Chevrolet cars, or the Nike "swoosh" that appears on shoes and athletic gear. It is a way for consumers to recognize and differentiate products from different companies.
For example, Fanta has a trademark on their orange drink, which distinguishes it from other companies that also make orange drinks.
