For the time being (3,3)
I believe the answer is:
pro tem
'for the time being' is the definition.
(synonyms)
This is all the clue.
(Other definitions for pro tem that I've seen before include "'For the time being (3,3)'" , "Informally, for the time being" , "For the time being, to the old Romans in short" , "For the present" , "not indefinitely extended" .)
