Other forms: reinvented; reinventing; reinvents
To reinvent something is to completely change or remake it so thoroughly that it seems brand new. The driverless car is going to reinvent the way people think about driving.
When the earliest movies with sound were released, it seemed to reinvent film. And, when libraries started incorporating more technology and getting rid of card catalogs, they reinvented research. You can also literally reinvent something, by bringing it back: "They plan to reinvent their grandmother's lost recipe for homemade root beer." To "reinvent the wheel" means to do something redundantly — to waste time on something that's already been done.
