Browning's before (3)
I believe the answer is:
ere
'browning's before' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ere that I've seen before include "Old word for before" , "Archaic word for before - a palindrome" , "One who steals" , "Before (poetic)" , "Before (in poetry)" .)
