Heretofore (6)
I believe the answer is:
erenow
'heretofore' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for erenow that I've seen before include "Before this time (arch.)" , "previously" , "Hitherto" , "Before the present" , "Before this time (poet.)" .)
