Balance books for ladies (6)
I believe the answer is:
others
'balance' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'books for ladies' is the wordplay.
'books' becomes 'ot' (Old Testament).
'for ladies' becomes 'hers' (I can't justify this - if you can you should believe this answer much more).
'ot'+'hers'='OTHERS'
Can you help me to learn more?
(Other definitions for others that I've seen before include "He rots (anag.)" , "The rest" , "People in throes - not us" , "Different from those already mentioned" , "Not these, alternatives" .)
