Work around edge in proper manner (6)
I believe the answer is:
primly
'in proper manner' is the definition.
'work around edge' is the wordplay.
'work' becomes 'ply' (I've seen this before**).
'around' is an insertion indicator.
'edge' becomes 'rim' (rim is a kind of edge).
'ply' enclosing 'rim' is 'PRIMLY'.
(Other definitions for primly that I've seen before include "In a stiffly correct manner" , "neatly and with precision" .)
