Items on the menu to finish off in cooker (6)
I believe the answer is:
agenda
'items on the menu' is the definition.
'agenda' can be an answer for 'menu' (I've seen this before). I'm not sure about the 'items on the' bit.
'finish off in cooker' is the wordplay.
'finish off' becomes 'end' (to finish is to come to an end).
'in' means one lot of letters goes inside another.
'cooker' becomes 'aga' (I've seen this before).
'end' placed inside 'aga' is 'AGENDA'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for agenda that I've seen before include "Programme of a meeting" , "plan of things to be done" , "Topics for a meeting" , "things still to be done" , "Programme of business" .)
