Point out affluent German kingdom (5)
I believe the answer is:
reich
'kingdom' is the definition.
(I know that Reich is a type of empire)
'point out affluent german' is the wordplay.
I cannot quite see how this works, but
'point' could be 'e' (compass point) and 'e' is located in the answer.
'affluent' could be 'rich' (similar in meaning) and 'rich' is found in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for reich that I've seen before include "Old foreign state" , "Old German state" , "The German state during the Nazi regime was the third one" , "Hitler's was the Third" , "US composer" .)
