According to the online dictionary Dictionary.com, one of the definitions of "to walk" is to proceed through, over, or upon at a moderate pace on foot. It gives the two examples below.
(ex) walking London streets by night; walking the floor all night
This is a "new" definition for me because you can put an object after it. Usually, you have to use a preposition after it. For example, to walk across the stage and to walk in the park.
I am going to make up an example using this definition below.
(1) He likes to walk the stairs instead of taking the elevator.
Is it correct to say "walk the stairs" based on this particular definition? Thanks for your help.
