Spaniard, maybe a pure one corrupted (8)
I believe the answer is:
european
'spaniard maybe' is the definition.
(I know that Spaniard is a type of European)
'a pure one corrupted' is the wordplay.
'corrupted' indicates anagramming the letters.
'a'+'pure'+'one'='apureone'
'apureone' anagrammed gives 'EUROPEAN'.
(Other definitions for european that I've seen before include "Native of a continent" , "Of a certain continent" , "EU native" , "Swede, perhaps?" , "Inhabitant of the second smallest continent" .)
