At this point, there's no point! (3)
I believe the answer is:
now
'at this point' is the definition.
(thesaurus)
'there's no point' is the wordplay.
'there's' is a charade indicator (letters next to each other).
'point' becomes 'w' (W is an example**).
'no' put next to 'w' is 'NOW'.
(Other definitions for now that I've seen before include "At the present time" , "Immediately" , "The present moment" , "straight away" , "At present, this instant" .)
