Hides hospital assets carelessly (7)
I believe the answer is:
stashes
'hides' is the definition.
(I've seen this in another clue)
'hospital assets carelessly' is the wordplay.
'hospital' becomes 'H' (abbreviation for hospital).
'carelessly' indicates anagramming the letters.
'h'+'assets'='hassets'
'hassets' is an anagram of 'STASHES'.
(Other definitions for stashes that I've seen before include "Hidden supplies or stores" , "Secret stores" .)
