Yielding some product, I left (7)
I believe the answer is:
ductile
'yielding' is the definition.
(thesaurus)
'some product i left' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'DUCTILE' is hidden within 'product i left'.
(Other definitions for ductile that I've seen before include "(Of metal) able to be drawn out into wire" , "Easily led" , "Able to be drawn out thinly" .)
