Edward after surgery made choice (5)
I believe the answer is:
opted
'made choice' is the definition.
The definition suggests a past participle verb which matches the answer.
'edward after surgery' is the wordplay.
'edward' becomes 'ted'.
'after' means one lot of letters go next to another.
'surgery' becomes 'op' (short for operation).
'ted' put after 'op' is 'OPTED'.
Can you help me to learn more?
(Other definitions for opted that I've seen before include "Chosen - elected" , "'Decided on, chose (5)'" , "Chose from depot" , "Made choice, selected" , "Plumped (for)" .)
