Carry out, accomplish (7)
I believe the answer is:
execute
I believe this is a double definition.
'carry out' is the first definition.
(executing is a kind of carrying out)
'accomplish' is the second definition.

(Other definitions for execute that I've seen before include "Inflict capital punishment upon" , "Discharge" , "shoot" , "Kill someone" , "Carry into effect" .)
