Cope with East German not getting rest (6)
I believe the answer is:
manage
'cope with' is the definition.
(I've seen this in another clue)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for manage that I've seen before include "Control; cope" , "Be in charge of something" , "Contrive" , "Organise" , "Run (eg, company)" .)
