Elderly beginning to adore absorbing new programme (6)
I believe the answer is:
agenda
'programme' is the definition.
(agenda is a kind of programme)
'elderly beginning to adore absorbing new' is the wordplay.
'elderly' becomes 'aged' ('aged' can be a synonym of 'elderly').
'beginning to' says to take the initial letters.
'absorbing' indicates putting letters inside.
'new' becomes 'n'.
The initial letter of 'adore' is 'a'.
'aged'+'a'='ageda'
'ageda' enclosing 'n' is 'AGENDA'.
(Other definitions for agenda that I've seen before include "List of matters to be discussed at a meeting" , "List of business for a committee meeting" , "Topics for a meeting" , "Meeting's topics" , "Schedule of items for meeting" .)
