You can add static text to the creek label, just as you did in the annotation template. Use the Concat function again.
In this exercise, you use Concat to add the static text "Waterway:" to the creek labels.
To add static text to the label
When you add a static text entry, surround it with single quotes. To include a space between the static text and the following property, put the space inside the closing single quote mark.
The expression now looks like this:
CONCAT ( 'Waterway: ' , NAME )
Zoom in to the same area around the cloverleaf in the middle of town. The creeks now display the new labels with the static text and creek names.
