Note: It's important to remember that generonyms can be used both generically and specifically. For example, you could say "I need a Band-Aid" or "I need a brand-name Band-Aid". However, the brand name is often used generically.
Also, the status of a generonym can change over time. A brand name might be used generically for a period of time, but then lose its status if another brand becomes more popular or if the original brand itself stops being marketed.
