They were banned from moving debris (6)
I believe the answer is:
brides
'they were banned' is the definition.
The definition suggests an adverb but the answer is not.
'moving debris' is the wordplay.
'moving' indicates an anagram.
'debris' with letters rearranged gives 'BRIDES'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for brides that I've seen before include "trains behind them?" , "'Seven - - for Seven Brothers' (film)" , "Girls about to marry" , "Book by Evelyn Waugh" , "Debris (anag)" .)
