The good man a bad man took in (6)
I believe the answer is:
curate
'the good man' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'a bad man took in' is the wordplay.
'a bad man' becomes 'cur' (I can't justify this - if you can you should believe this answer much more).
'took in' becomes 'ate' (take in can mean to eat).
'cur'+'ate'='CURATE'
Can you help me to learn more?
(Other definitions for curate that I've seen before include "look after collection" , "Clergyman assisting a vicar" , "Churchman" , "Take care of collection" , "A truce (anag)" .)
