What's left, for example, in moulded clay (6)
I believe the answer is:
legacy
'what's left' is the definition.
(what's left behind by a deceased person)
'example in moulded clay' is the wordplay.
'example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'in' is an insertion indicator.
'moulded' indicates anagramming the letters.
'clay' is an anagram of 'lacy'.
'eg' inserted within 'lacy' is 'LEGACY'.
'for' acts as a link.
(Other definitions for legacy that I've seen before include "What's left" , "Inheritance" , "A bequest, something left in a will" , "Heritage" , "Birthright" .)
