Work with Eurocentric leader helping campaign (9)
I believe the answer is:
operation
'campaign' is the definition.
(thesaurus)
'work with eurocentric leader helping' is the wordplay.
'work' becomes 'op' (abbreviation for opus).
'with' says to put letters next to each other.
'leader' suggests taking the first letters.
'helping' becomes 'ration' (a ration is a serving or helping).
The initial letter of 'eurocentric' is 'e'.
'op'+'e'+'ration'='OPERATION'
(Other definitions for operation that I've seen before include "Act of surgery" , "management" , "Handling" , "battle" , "In hospital procedure" .)
