List of things to be done or discussed (6)
I believe the answer is:
agenda
'list of things to be done or discussed' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for agenda that I've seen before include "List of items to be discussed" , "List of items for committee to consider" , "Programme of a meeting" , "Meeting's topics" , "List of business for a committee meeting" .)
