I find EU surprisingly integrated (7)
I believe the answer is:
unified
'integrated' is the definition.
(I know this)
'i find eu surprisingly' is the wordplay.
'surprisingly' is an anagram indicator (a surprising ordering of the letters).
'i'+'find'+'eu'='ifindeu'
'ifindeu' anagrammed gives 'UNIFIED'.
(Other definitions for unified that I've seen before include "Brought together as one" , "Joined together" , "Made one" .)
