Not anymore (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
once
'not anymore' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for once that I've seen before include "One-time - one time" , "Just as a single occurrence" , "in bygone days" , "in days of yore?" , "At some former time" .)
