Sibling is fine at empty library with bridge player in New York (8)
I believe the answer is:
brooklyn
'in new york' is the definition.
('Brooklyn' is part of 'new york')
'sibling is fine at empty library with' is the wordplay.
'sibling' becomes 'bro' (I've seen this before).
'is fine' becomes 'ok'.
'at' says to put letters next to each other.
'empty library with' becomes 'lyn' (I am not sure about this - if you are sure you should believe this answer much more).
'bro'+'ok'+'lyn'='BROOKLYN'
'bridge player' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for brooklyn that I've seen before include "part of Long Island?" , "New York borough with famous bridge." , "District and bridge in New York" , "NYC borough, book and film" , "New York area" .)
