Shoddy stuff which hospital chucked out (3)
I believe the answer is:
tat
'shoddy stuff' is the definition.
(I've seen this before)
'which hospital chucked out' is the wordplay.
'which' becomes 'that'.
'hospital' becomes 'h'.
'chucked out' suggests deleting specific letters.
'that' with 'h' removed is 'TAT'.
(Other definitions for tat that I've seen before include "Tawdry stuff" , "What you get for tit" , "trashy clothing" , "Worthless items" , "Shoddy stuff (colloq.)" .)
