Chose to make a work Edwardian (5)
I believe the answer is:
opted
'chose' is the definition.
(to opt for something is to choose it)
'a work edwardian' is the wordplay.
'a work' becomes 'op' (common 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)'" .)
