Rebellions at New York office a daily event (6,3)
I believe the answer is:
rising sun
'office a daily event' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'rebellions at new york' is the wordplay.
'rebellions' becomes 'risings' ('rising' can be a synonym of 'rebellion').
'at' is a charade indicator (letters next to each other).
'new york' becomes 'un' (I can't explain this - if you can you should believe this answer much more).
'risings'+'un'='RISING SUN'
Can you help me to learn more?
(Other definitions for rising sun that I've seen before include "Japanese standardisation" , "Dawn" , "Part of standard for Japanese" .)
