Graceful in approach, perhaps (6)
I believe the answer is:
comely
'graceful' is the definition.
(I've seen this before)
'approach perhaps' is the wordplay.
'approach' becomes 'come' (e.g. as imperative).
'perhaps' becomes 'ly' (I can't explain this - if you can you should believe this answer much more).
'come'+'ly'='COMELY'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for comely that I've seen before include "Fair (but not lovely!)" , "Pleasing, graceful" , "Old word for good-looking, say a lass" , "Quite good-looking" , "Pleasant looking" .)
