Other forms: widgets
A widget is a tool that's perfect for a specific job, like the widget you use to open the door of your ancient car, or the widgets on your webpage that link to your social media accounts.
Widget is commonly used to mean "gadget," the word that inspired this American English term. If your grandpa tinkers with tools and gizmos in his garage, he's definitely got widgets in there. Sometimes theoretical products or goods are also called widgets: "Say you build a widget factory right here on Main Street..." When it comes to computers, a widget is code that does a specific job, often taking you from one site to another in a single click.
