Foreigner from East ran Germany (8)
I believe the answer is:
stranger
'foreigner' is the definition.
(thesaurus)
'from east ran germany' is the wordplay.
'from' says the answer is hidden in the clue.
'STRANGER' is hidden in the letters of 'east ran germany'.
(Other definitions for stranger that I've seen before include "Newcomer, alien" , "Person in place or company to which he does not belong" , "someone making nuisance call?" , "The unknown one is more unusual" , "Outsider" .)
