A man prepares leaves for a book (7)
I believe the answer is:
hebrews
'for a book' is the definition.
I can't judge whether this definition defines the answer.
'a man prepares' is the wordplay.
'a man' becomes 'he'.
'prepares' becomes 'brews' (I can't justify this - if you can you should give a lot more credence to this answer).
'he'+'brews'='HEBREWS'
'leaves' acts as a link.
Can you help me to learn more?
(Other definitions for hebrews that I've seen before include "An NT epistle" , "book before James" , "Jews" , "Memers of an ancient Semitic peoples" .)
