Disturbed grave, silent and deathless (11)
I believe the answer is:
'deathless' is the definition.
'disturbed grave silent' is the wordplay.
'disturbed' indicates anagramming the letters.
'gravesilent' with letters rearranged gives 'EVERLASTING'.
'and' acts as a link.
(Other definitions for everlasting that I've seen before include "description of the rest Romeo set up here?" , "Undying" , "Eternal" , "describes Wonka's gobstoppers" , "Unceasing" .)
