Some hospital ungenerously making charge (5)
I believe the answer is:
lunge
'charge' is the definition.
(I've seen this before)
'some hospital ungenerously making' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'LUNGE' is hidden in the letters of 'hospital ungenerously making'.
(Other definitions for lunge that I've seen before include "Trust forward as with sword" , "Sudden push forward" , "Fall upon" , "dive" , "Impulsive move" .)
