Making a point about a hole (3)
I believe the answer is:
gap
'a hole' is the definition.
(thesaurus)
'making a point about' is the wordplay.
'about' indicates the answer is hidden within the clue.
'GAP' can be found hidden inside 'making a point'.
(Other definitions for gap that I've seen before include "Interval, break" , "Disparity" , "Empty space between things" , "Break in continuity" , "Small opening" .)
