Some depart nervously for get together (7)
I believe the answer is:
partner
'get together' is the definition.
(thesaurus)
'some depart nervously for' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'PARTNER' is hidden in the letters of 'depart nervously for'.
(Other definitions for partner that I've seen before include "sometimes joining in crime" , "Associate, in business or private life" , "One sharing home or business" , "Accomplice" , "south to north, perhaps" .)
