EU collecting money raised for alliance (5)
I believe the answer is:
unite
'eu collecting money raised for alliance' is the definition.
I can't judge whether this defines the answer.
'eu collecting money raised' is the wordplay.
'collecting' indicates putting letters inside.
'money' becomes 'tin' (old-fashioned slang term for money).
'raised' is a reversal indicator (going up in a down clue).
'eu' enclosing 'tin' is 'etinu'.
'etinu' backwards is 'UNITE'.
Can you help me to learn more?
(Other definitions for unite that I've seen before include "Couple" , "Club together" , "Bring together, become one" , "Join together, merge" , "Combine - join" .)
