Relocate German in Abu Dhabi, perhaps (8)
I believe the answer is:
emigrate
'relocate' is the definition.
(thesaurus)
'german in abu dhabi perhaps' is the wordplay.
'german' becomes 'g' (abbreviation).
'in' means one lot of letters goes inside another.
'abu dhabi perhaps' becomes 'emirate' (Abu Dhabi is one of the United Arab Emirates).
'g' inserted within 'emirate' is 'EMIGRATE'.
(Other definitions for emigrate that I've seen before include "Leave one's country to live elsewhere" , "Move overseas" , "Leave homeland" , "Go to live and work in another country" , "Leave home" .)
