You may see it before long (3)
I believe the answer is:
ere
'you may see it before long' 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 "Before (literary)" , "Before (lit.)" , "Before (poetic)" , "Archaic word for before - a palindrome" , "Before, poetically" .)
