Widgets are mini-apps (e.g., weather, clock, calendar, etc.) that can be added to a Home screen. They aren't the same as shortcuts as they generally display info and take up more space than a single icon.
From a Home screen, press and hold a blank area of the screen.
From the Home screen menu, tap Add apps and widgets.
Tap the Dropdown menu (located toward the left) then ensure Widgets is selected.
Drag the widget to the preferred Home screen location then release.
For the widget to be successfully added, there must be sufficient space on the screen.
If applicable, configure any additional options to activate widget.
Options vary depending upon the type of widget.
