Provisional offering from Pinter impressed (7)
I believe the answer is:
interim
'provisional' is the definition.
(thesaurus)
'from pinter impressed' is the wordplay.
'from' says the answer is hidden in the clue.
'INTERIM' is hidden in the letters of 'pinter impressed'.
'offering' acts as a link.
(Other definitions for interim that I've seen before include "acting" , "Meantime - provisional" , "temporary period" , "Caretaker" , ", I'm put in grave situation initially" .)
