Refuse to transport brides (6)
I believe the answer is:
debris
'refuse' is the definition.
(I've seen this in another clue)
'transport brides' is the wordplay.
'transport' indicates an anagram (letters are transported elsewhere).
'brides' with letters rearranged gives 'DEBRIS'.
'to' is the link.
(Other definitions for debris that I've seen before include "Scattered remains" , "Scattered rubbish" , "Rubble, heap of broken pieces" , "Scattered wreckage" , "Broken remains" .)
