Still rising in late years (3)
I believe the answer is:
yet
'still' is the definition.
(yet can mean still or so far)
'rising in late years' is the wordplay.
'rising' is a reversal indicator (in a down clue, letters go up).
'in' indicates the answer is hidden within the clue.
'tey' is hidden in the letters of 'late years'.
'tey' written backwards gives 'YET'.
(Other definitions for yet that I've seen before include "Though; still" , "Still, even" , "Up to this time and continuing" , "Up till now" , "Still; nevertheless" .)
