Money backing writer? A bloomer there, perhaps (5,3)
I believe the answer is:
bread bin
'a bloomer there perhaps' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'money backing writer?' is the wordplay.
'money' becomes 'bread' (bread is slang for money).
'backing' is a reversal indicator.
'writer?' becomes 'nib' (something which writes).
'nib' reversed gives 'bin'.
'bread'+'bin'='BREAD-BIN'
Can you help me to learn more?
(Other definitions for bread bin that I've seen before include "Receptacle for loaf" , "Loaf holder" , "Food container" , "Loaf container" .)
