Debris from clubs in crazy rag week (8)
I believe the answer is:
wreckage
'debris' is the definition.
(I've seen this before)
'clubs in crazy rag week' is the wordplay.
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'in' indicates putting letters inside.
'crazy' indicates anagramming the letters.
'rag'+'week'='ragweek'
'ragweek' anagrammed gives 'wrekage'.
'c' going into 'wrekage' is 'WRECKAGE'.
'from' acts as a link.
(Other definitions for wreckage that I've seen before include "Ruined remains" , "Damaged remains" , "Sign of misfortune at sea" , "Remains of something destroyed, at sea perhaps" , "Crash pieces" .)
