Suggest writing about work (7)
I believe the answer is:
propose
'suggest' is the definition.
('propose' can be a synonym of 'suggest')
'writing about work' is the wordplay.
'writing' becomes 'prose' (I've seen this in other clues).
'about' indicates putting letters inside.
'work' becomes 'op' (abbreviation for opus).
'prose' going around 'op' is 'PROPOSE'.
(Other definitions for propose that I've seen before include "Put forward for consideration" , "Put forward (motion)" , "Request" , "Tender" , "Put forward (an idea)" .)
