Be craving small possessions (10)
I believe the answer is:
belongings
'possessions' is the definition.
(belonging is a kind of possession)
'be craving small' is the wordplay.
'craving' becomes 'longing' (longing for something is craving it).
'small' becomes 's' (abbreviation - e.g. clothes size).
'be'+'longing'+'s'='BELONGINGS'
(Other definitions for belongings that I've seen before include "stuff" , "property" , "Personal effects" .)
