Litter found in raised bed, upset entitled man (6)
I believe the answer is:
debris
'litter' is the definition.
(I've seen this in another clue)
'raised bed upset entitled man' is the wordplay.
'raised' is a reversal indicator (going up in a down clue).
'upset' says the letters should be written in reverse.
'entitled man' becomes 'sir' (sir is a kind of man. I am not sure about the 'entitled' bit.).
'bed' backwards is 'deb'.
'sir' back-to-front is 'ris'.
'deb'+'ris'='DEBRIS'
'found in' is the link.
Can you help me to learn more?
(Other definitions for debris that I've seen before include "Detritus, rubbish" , "Fragments of rubbish" , "Fragments of wreckage" , "Scattered broken pieces, rubble" , "Rocky fragments" .)
