At this point said “Listen!” (4)
I believe the answer is:
here
'at this point' is the definition.
(thesaurus)
'said listen' is the wordplay.
'said' indicates a 'sounds like' (homophone) clue.
'listen' becomes 'hear' (I've seen this before).
'hear' is a homophone of 'HERE'.
(Other definitions for here that I've seen before include "In attendance" , "To hand" , "On this spot" , "In this place - present" , ""___ be dragons" (old map inscription?)" .)
