Homonym: popup (Window)
A "popup" refers to a graphical user interface element that appears suddenly on a screen, often to provide information or prompt user interaction. Commonly used on websites, popups can display advertisements, notifications, or forms. They can be triggered by various actions, such as clicking a link or after a certain time on a page.
Popups can be beneficial for engaging users, but they can also be intrusive if overused. Many web browsers and applications offer settings to block or manage popups, allowing users to control their experience. Effective use of popups can enhance user experience when done thoughtfully.
