The verge=* tag is used to indicate the presence of a 
road verge on a highway.
Verges are strips of groundcover such as grasses or low shrubs which are typically located between roadways and sidewalks.
There may also be flowers, shrubs, or trees planted within verges.
These areas improve pedestrian safety and often function as important conservation spaces.
Note that, in some regions, managed roadside spaces are sometimes referred to as verges even when no sidewalk is present.
Values
As with sidewalks, there are multiple parallel tagging approaches in use for mapping verges.
"Left" and "Right" below refer to the side of the way - refer to Forward & backward, left & right for more information.
As a property of a highway=* 
way, with "sidedness" suffixes:
verge:left=*/verge:right=*/verge:both=*- verge:side=
separate- There is a verge on the indicated side(s) of this way, and it is mapped separately. - verge:side=
yes- There is a verge on the indicated side(s) of this way. It may or may not be mapped separately. - verge:side=
no- There is not a verge on the indicated side(s) of this way.
- verge:side=
As a property of a highway=* way, with a value of verge=*:
verge=yes- There is a verge associated with this way. Ambiguous, as it is not clear which side(s) of the way have a verge.verge=left- There is a verge on the left of this way. Equivalent toverge:left=yes+verge:right=no.verge=right- There is a verge on the right of this way. Equivalent toverge:right=yes+verge:left=no.verge=both- There is a verge on both sides of this way. Equivalent toverge:both=yes.verge=no- There is not a verge on either side of this way. Equivalent toverge:both=no.
Indicating that a separately mapped area is itself a verge:
- In this case, the adjacent highway should be tagged with verge:side=
separate.
Additional details
Additional information may be added within the verge:*=* namespace, such as:
- verge:side:
width=2specifying the unit in meters - verge:side:
width=5'specifying the unit in feet - verge:side:
surface=grass

History
This tag was first used in 2009 by SK53 to explicitly capture detail on a minor road which personal experience showed was dangerous for pedestrians.
