Ottoman masters finish in meeting schedules (7)
I believe the answer is:
agendas
'meeting schedules' is the definition.
(I've seen this in another clue)
'ottoman masters finish in' is the wordplay.
'ottoman masters' becomes 'agas' (I can't justify this - if you can you should believe this answer much more).
'finish' becomes 'end' (synonyms).
'in' means one lot of letters goes inside another.
'agas' enclosing 'end' is 'AGENDAS'.
Can you help me to learn more?
(Other definitions for agendas that I've seen before include "Lists of matters to be taken up at meetings" , "Committee-matters" , "programmes" , "Schedules" , "Orders of business" .)
