Brought back, for the clergyman, one pound of meat (5)
I believe the answer is:
liver
'pound of meat' is the definition.
'liver' can be an answer for 'meat' (liver is a kind of meat). I'm unsure of the 'pound of' bit.
'brought back for the clergyman one' is the wordplay.
'brought' becomes 'l' (I can't justify this - if you can you should believe this answer much more).
'back for' says the letters should be written backwards (I've seen 'backing for' mean this).
'the clergyman' becomes 'rev' (short for reverend).
'one' becomes 'i' (Roman numeral).
'rev'+'i'='revi'
'revi' reversed gives 'iver'.
'l'+'iver'='LIVER'
Can you help me to learn more?
(Other definitions for liver that I've seen before include "Abdominal organ" , "Bodily organ" , "Organ; reddish-brown" , "Large gland" , "Organ damaged by excess alcohol" .)
