Where numbers are called, not to share writer’s point about everything (5,4)
I believe the answer is:
bingo hall
'where numbers are called not' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'share writer's point about everything' is the wordplay.
'share' becomes 'hog' (I can't explain this - if you can you should believe this answer much more).
'writer's point' becomes 'nib' (nib of a pen, something which writes).
'about' says the letters should be written backwards.
'everything' becomes 'all' (all things).
'hog'+'nib'='hognib'
'hognib' written backwards gives 'bingoh'.
'bingoh'+'all'='BINGO HALL'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for bingo hall that I've seen before include "Where to find two little ducks" , "entertainment venue" , "two fat ladies here?" .)
