Sign able to confuse some Europeans (8)
I believe the answer is:
belgians
'europeans' is the definition.
(Belgian is an example)
'sign able to confuse' is the wordplay.
'to confuse' is an anagram indicator.
'sign'+'able'='signable'
'signable' anagrammed gives 'BELGIANS'.
'some' acts as a link.
(Other definitions for belgians that I've seen before include "Natives of Antwerp, say" , "Nationality of citizens of Liege" , "Singable citizens of Brussels" , "Nationality of natives of Brussels" .)
