A way to get two points across at discussion (12)
I believe the answer is:
conversation
'discussion' is the definition.
(thesaurus)
'a way to get two points across at' is the wordplay.
'a way to get two points' becomes 'conversion' (rugby term).
'across' indicates putting letters inside.
'conversion' placed around 'at' is 'CONVERSATION'.
(Other definitions for conversation that I've seen before include "discussion" , "22 between people" , "dialogue" , "Talk, chat" , "Spoken exchange" .)
