Embrace European giant (4)
I believe the answer is:
huge
'giant' is the definition.
(both can mean large)
'embrace european' is the wordplay.
'embrace' becomes 'hug' (synonyms).
'european' becomes 'E' (abbreviation e.g. EU).
'hug'+'e'='HUGE'
(Other definitions for huge that I've seen before include "Gigantic" , "Colossal" , "Enormous" , "giant" , "Mammoth" .)
