A craving to be settled (6)
I believe the answer is:
agreed
'be settled' is the definition.
(settled can mean agreed or decided)
'a craving' is the wordplay.
'craving' becomes 'greed' (greed is craving too much).
'a'+'greed'='AGREED'
'to' is the link.
(Other definitions for agreed that I've seen before include "Assented, acquiesced" , "very well" , "acceptable" , "Mutually settled" , "Said yes" .)
