ELI5: Explain Like I'm 5

Functional item

A functional item is something that is designed to be used for a specific purpose. For example, a fork is a functional item because it is designed to help you eat by spearing food and bringing it to your mouth. A chair is also a functional item because it is designed to be sat on and provide a place to rest. These items are not just randomly put together but have been carefully thought out by designers to suit their intended use. So, when you use a functional item, you can be sure that it will work as it is meant to and help make your life easier.
