He plans to produce a book (7)
I believe the answer is:
hebrews
'a book' is the definition.
(book of bible)
'he plans to' is the wordplay.
'plans to' becomes 'brews' (I am not sure about this - if you are sure you should believe this answer much more).
'he'+'brews'='HEBREWS'
'produce' is the link.
Can you help me to learn more?
(Other definitions for hebrews that I've seen before include "Jews" , "book before James" , "Memers of an ancient Semitic peoples" , "An NT epistle" .)
