Fragments from inside Bristol (6)
I believe the answer is:
debris
'fragments' is the definition.
(I've seen this in another clue)
'from inside bristol' is the wordplay.
'from' indicates a hidden word.
'DEBRIS' is hidden within 'inside bristol'.
(Other definitions for debris that I've seen before include "Fragments of wreckage" , "Scattered wreckage" , "Refuse remains" , "Broken remains" , "Refuse, litter" .)
