Son put away stuff (4)
I believe the answer is:
sate
'stuff' is the definition.
(thesaurus)
'son put away' is the wordplay.
'son' becomes 's' (genealogical abbreviation for son).
'put away' becomes 'ate' (I've seen this in other clues).
's'+'ate'='SATE'
(Other definitions for sate that I've seen before include "Malaysian dish" , "Supply to excess" , "replete" , "Fulfil to excess" , "Satisfy more than fully" .)
