Temporary, provisional (7)
I believe the answer is:
interim
I believe this is a double definition.
'temporary' is the first definition.
(similar in meaning)
'provisional' is the second definition.
(I've seen this before)
(Other definitions for interim that I've seen before include "Stopgap" , "not there for ever" , "acting" , ", I'm put in grave situation initially" , "Meanwhile" .)
