Play with ball, breaking some furniture (7)
I believe the answer is:
tallboy
'some furniture' is the definition.
(tallboy is a kind of furniture)
'play with ball breaking' is the wordplay.
'play' becomes 'toy' ('toy' can be a synonym of 'play').
'with' is an insertion indicator.
'breaking' is an anagram indicator.
'ball' with letters rearranged gives 'allb'.
'toy' going around 'allb' is 'TALLBOY'.
(Other definitions for tallboy that I've seen before include "Chest of drawers in two sections" , "Item of furniture" , "Cabinet" , "Two-part chest of drawers" , "Type of chest of drawers" .)
