Confuse Parsi and European (8)
I believe the answer is:
'european' is the definition.
(someone from Spain)
'confuse parsi and' is the wordplay.
'confuse' is an anagram indicator.
'parsiand' with letters rearranged gives 'SPANIARD'.
(Other definitions for spaniard that I've seen before include "Slope-measuring instrument" , "Native of southern European country" , "Malaga man or woman, perhaps?" , "Person from Eurozone" , "European national" .)
