Cut times in hospital department (3)
I believe the answer is:
axe
'cut' is the definition.
(both can mean to cancel or remove)
'times in hospital department' is the wordplay.
'times' becomes 'x' (x resembles the multiplication or times sign).
'in' indicates putting letters inside.
'hospital department' becomes 'ae' (A and E, Accident and Emergency department).
'x' going into 'ae' is 'AXE'.
(Other definitions for axe that I've seen before include "Hack" , "saw alternative?" , "Cancel" , "flower in Devon" , "Cutter" .)
