Some made his cellar burst open (7)
I believe the answer is:
dehisce
'burst open' is the definition.
(to dehisce is to burst open)
'some made his cellar' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'DEHISCE' is hidden in the letters of 'made his cellar'.
(Other definitions for dehisce that I've seen before include "rupture" , "Seeds burst from pod" , "Gape" , "Burst open, ejecting seeds" .)
