Agree the friend must come over for the conference (7)
I believe the answer is:
palaver
'the conference' is the definition.
(I've seen this before)
'agree the friend must come over' is the wordplay.
I cannot quite understand how this works, but
'friend' could be 'pal' (pal is a kind of friend) and 'pal' is found within the answer.
The remaining letters 'aver' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for palaver that I've seen before include "Rigmarole" , "Time-consuming business" , "Prolonged fuss" , "Confused and empty talk" , "Fuss and bother" .)
