Execute like supermarket purchases, for example (5,3)
I believe the answer is:
carry out
'execute' is the definition.
(synonyms)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for carry out that I've seen before include "Takeaway (Sc. & US)" , "Effect, or bear from house" , "Make good" , "Remove - execute" , "Realise" .)
