Hoped-for future relief with fat dispersed (9)
I believe the answer is:
afterlife
'hoped-for future' is the definition.
(I've seen this before)
'relief with fat dispersed' is the wordplay.
'with' means one lot of letters go next to another.
'dispersed' indicates anagramming the letters.
'relief'+'fat'='relieffat'
'relieffat' anagrammed gives 'AFTERLIFE'.
(Other definitions for afterlife that I've seen before include "Existence following death" , "Existence beyond death" , "Post-death existence" , "Existence beyond the grave" , "Hoped-for future" .)
