Fulfil Scottish takeaway order (5,3)

I believe the answer is:
carry out
'fulfil' is the definition.
(synonyms)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for carry out that I've seen before include "one can't stay for this meal" , "Effect, or bear from house" , "Realise" , "Remove - execute" , "Take away" .)
