Complete implement (7)
I believe the answer is:
execute
This clue is a double definition.
'complete' is the first definition.
(I know that execute is a type of complete)
'implement' is the second definition.
(I know that execute is a type of implement)
(Other definitions for execute that I've seen before include "Maybe send to chair" , "Finish off" , "ice" , "Discharge" , "Get it done" .)
