Moved slowly and won, just (5)
I believe the answer is:
edged
'moved slowly' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for edged that I've seen before include "Hemmed" , "Rimmed" , "Made moves that were gradual" , "Fringed" , "sharp" .)
