Celebrity mostly on ecstasy up until this point (6)
I believe the answer is:
erenow
'celebrity mostly' is the definition.
I can't judge whether this defines the answer.
'on ecstasy up until this point' is the wordplay.
'on' is a charade indicator (letters next to each other).
'ecstasy up' becomes 'no' (I can't explain this - if you can you should believe this answer much more).
'until' becomes 'ere' (I've seen this in another clue).
'this point' becomes 'W' (West).
'no' put after 'ere' is 'ereno'.
'ereno'+'w'='ERENOW'
Can you help me to learn more?
(Other definitions for erenow that I've seen before include "Before the present" , "Before this time (arch.)" , "Before this time (poet.)" , "previously" , "Hitherto" .)
