Coming together to raise standard (5,4)
I believe the answer is:
union jack
'standard' is the definition.
(I know that Union Jack is a type of standard)
'coming together to raise' is the wordplay.
'coming together' becomes 'union' (I am not sure about this - if you are sure you should believe this answer much more).
'to raise' becomes 'jack' (jacking is a kind of raising).
'union'+'jack'='UNION JACK'
Can you help me to learn more?
(Other definitions for union jack that I've seen before include "Colours" , "standard for us" , "National flag of U.K." , "appears up the pole" , "The British flag" .)
