German with something to lose perhaps (6)
I believe the answer is:
dieter
'german' is the definition.
(common German name)
'something to lose perhaps' is the wordplay.
I cannot really see how this works, but
'something' could be 'er' (I've seen this in other clues) and 'er' is located in the answer.
The remaining letters 'diet' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'with' acts as a link.
Can you help me to learn more?
(Other definitions for dieter that I've seen before include "who wants to lose 13 [BULK]" , "German fellow" , "fellow who'll eat less?" , "person unlikely to eat much" , "One who's slimming" .)
