Some of us gathered in this place (4)
I believe the answer is:
here
'in this place' is the definition.
(synonyms)
'some of us gathered' is the wordplay.
'some of' indicates a hidden word.
'HERE' is hidden in the letters of 'us gathered'.
(Other definitions for here that I've seen before include "In this place - present" , "On this spot" , "final clue?" , "To hand" , "In attendance" .)
