Businesslike programme of a senior officer on half days (6)
I believe the answer is:
agenda
'businesslike programme' is the definition.
'agenda' can be an answer for 'programme' (agenda is a kind of programme). I'm not certain of the 'businesslike' bit.
'a senior officer on half days' is the wordplay.
'senior officer' becomes 'gen' (short for general, a senior army officer).
'on' says to put letters next to each other.
'half' means to take half the letters.
'days' with half the letters taken is 'da'.
'a'+'gen'+'da'='AGENDA'
'of' is the link.
Can you help me to learn more?
(Other definitions for agenda that I've seen before include "Table of business" , "Schedule - things to be done" , "List of items to be done" , "List of items to be discussed" , "List of business for a committee meeting" .)
