European trash: Antoine's (8)
I believe the answer is:
estonian
'european' is the definition.
(person from Estonia)
'trash antoine's' is the wordplay.
'trash' indicates an anagram.
'antoines' is an anagram of 'ESTONIAN'.
(Other definitions for estonian that I've seen before include "Balt" , "Eastern Europe" , "Baltic state national" , "From Tallinn, for example" , "Baltic state native" .)
