Bread is being imported this month (5)
I believe the answer is:
nisan
'this month' is the definition.
(month of the Hebrew calendar)
'bread is being imported' is the wordplay.
'bread' becomes 'nan' (variant spelling of naan).
'being imported' indicates putting letters inside.
'nan' enclosing 'is' is 'NISAN'.
(Other definitions for nisan that I've seen before include "month in Israel" , "when Passover begins" .)
