Escaped over water breaking pottery (9)
I believe the answer is:
'pottery' is the definition.
(I've seen this before)
'escaped over water breaking' is the wordplay.
'escaped' becomes 'fled' (I've seen this before).
'over' says the letters should be written backwards.
'breaking' is an anagram indicator.
'fled' in reverse letter order is 'delf'.
'water' is an anagram of 'tware'.
(Other definitions for delftware that I've seen before include "pottery" , "Decorative stuff" , "crockery" .)
