Latvian originally admitted to being a different European (7)
I believe the answer is:
belgian
'european' is the definition.
(Belgian is an example)
'latvian originally admitted to being a different' is the wordplay.
'originally' indicates taking the first letters.
'admitted to' means one lot of letters goes inside another.
'different' indicates an anagram.
The first letter of 'latvian' is 'l'.
'being'+'a'='beinga'
'beinga' with letters rearranged gives 'begian'.
'l' put inside 'begian' is 'BELGIAN'.
(Other definitions for belgian that I've seen before include "One from Liege, say" , "Hercule Poirot's nationality" , "Eg, Brussels native" , "Nationality of Rene Magritte" , "Bengali from a European state?" .)
