Lost rice scattered in the monastery (8)
I believe the answer is:
cloister
'the monastery' is the definition.
(I've seen this before)
'lost rice scattered' is the wordplay.
'scattered' is an anagram indicator.
'lost'+'rice'='lostrice'
'lostrice' is an anagram of 'CLOISTER'.
'in' is the link.
(Other definitions for cloister that I've seen before include "Covered monastic walkway" , "'Religious retreat, a convent, say (8)'" , "Monastic life" , "Covered passage round cathedral courtyard" , "Covered walkway around courtyard" .)
