Disgusting dirt in lift distressed hospital (5)
I believe the answer is:
filth
'disgusting dirt' is the definition.
(I've seen this before)
'lift distressed hospital' is the wordplay.
'distressed' is an anagram indicator.
'hospital' becomes 'h'.
'lift' with letters rearranged gives 'filt'.
'filt'+'h'='FILTH'
'in' is the link.
(Other definitions for filth that I've seen before include "Repulsive dirt" , "Dirt, obscene talk" , "Muck" , "Carrion" , "Disgusting dirt or obscenity" .)
