War criminal cuddles East German hospitality worker (7)
I believe the answer is:
hostess
'hospitality worker' is the definition.
'hostess' can be an answer for 'worker' (hostess is a kind of worker). I am not sure about the 'hospitality' bit.
'war criminal cuddles east german' is the wordplay.
'war criminal' becomes 'hess' (I can't explain this - if you can you should believe this answer much more).
'cuddles' indicates putting letters inside.
'east german' becomes 'ost' ('east' in German).
'hess' enclosing 'ost' is 'HOSTESS'.
Can you help me to learn more?
(Other definitions for hostess that I've seen before include "She looks after guests" , "Air stewardess" , "She entertains guests" , "party organiser" , "who welcomes guests?" .)
