Margins (5)
'margins' is the definition.
('edge' can be a synonym of 'margin')
This is all the clue.
(Other definitions for edges that I've seen before include "Fringes" , "They're farthest from the middle" , "Sharpened sides of blades" , "Slowly moves" , "Boundaries of a surface" .)
'margins' is the definition.
(border is a kind of margin)
This is all the clue.
(Other definitions for borders that I've seen before include "Boundary lines" , "Decorative edges" , "Perimeters" .)
