Caretaker returns bread after a month (7)
I believe the answer is:
janitor
'caretaker' is the definition.
(I've seen this before)
'returns bread after a month' is the wordplay.
'returns' says the letters should be written backwards.
'bread' becomes 'roti' (roti is a type of bread).
'after' says to put letters next to each other.
'a month' becomes 'Jan' (Jan is short for January).
'roti' in reverse letter order is 'itor'.
'itor' put after 'jan' is 'JANITOR'.
(Other definitions for janitor that I've seen before include "Caretaker (mainly US)" , "(In Scotland) school caretaker" , "Caretaker or doorkeeper" , "Person looking after building" , "One employed to clean and maintain a building" .)
