Me — native abroad to the south-east (10)
I believe the answer is:
vietnamese
'me native abroad to the south-east' is the definition.
I can't judge whether this defines the answer.
'me native abroad to the south-east' is the wordplay.
'abroad' indicates an anagram.
'to the south east' becomes 'SE' (abbreviation).
'me'+'native'='menative'
'menative' is an anagram of 'vietname'.
'vietname'+'se'='VIETNAMESE'
(Other definitions for vietnamese that I've seen before include "Asian language" , "Asians" , "People" , "oriental language" , "Natives of Hanoi" .)
