Chose to make a work Edwardian (5)
I believe the answer is:
opted
'chose' is the definition.
(I've seen this before)
'a work edwardian' is the wordplay.
'a work' becomes 'op' (abbreviation for opus).
'edwardian' becomes 'ted' (I can't explain this - if you can you should believe this answer much more).
'op'+'ted'='OPTED'
'to make' is the link.
Can you help me to learn more?
(Other definitions for opted that I've seen before include "Made choice, selected" , "Selected from depot" , "Decided as in 10 Across" , "Plumped (for)" , "'Decided on, chose (5)'" .)
