Discussion, meeting (6)
I believe the answer is:
powwow
I believe this clue is a double definition.
'discussion' is the first definition.
(powwow is a kind of discussion)
'meeting' is the second definition.
(I've seen this before)
(Other definitions for powwow that I've seen before include "Informal conference" , "Tribal conference" , "(Native American) conference or meeting" , "Meeting of Native Americans for discussion" , "North American native ceremony" .)
