Partly hide Bristol’s scattered rubbish (6)
I believe the answer is:
debris
'scattered rubbish' is the definition.
(I've seen this before)
'partly hide bristol's' is the wordplay.
'partly' indicates the answer is hidden within the clue.
'DEBRIS' is hidden within 'hide bristol'.
(Other definitions for debris that I've seen before include "Rebids for rubble" , "Scattered remains" , "Brides among rubble" , "Brides with pieces of rubble" , "aftermath of wild reception?" .)
