Tidied, as a lawn (5)
I believe the answer is:
edged
'tidied as a lawn' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for edged that I've seen before include "Advanced slowly sideways" , "Advance slowly sideways" , "Sidled" , "Made moves that were gradual" , "Moved furtively" .)
