Frozen in broken umbrella (4)
I believe the answer is:
numb
'frozen' is the definition.
(I've seen this before)
'in broken umbrella' is the wordplay.
'in' says the answer is hidden in the clue.
'NUMB' is hidden in the letters of 'broken umbrella'.
(Other definitions for numb that I've seen before include "Anaesthetised, unfeeling" , "Without sensation" , "Lacking feeling" , "Frozen" , "Unable to feel or think" .)
