Old plastic pierced the skin of nectarine and went through (11)
I believe the answer is:
experienced
'went through' is the definition.
('experience' can be a synonym of 'go through')
'old plastic pierced the skin of nectarine' is the wordplay.
'old' becomes 'ex' (prefix meaning former or onetime).
'plastic' indicates anagramming the letters (plastic can mean easily moulded).
'the skin of' says to hollow out the word (remove centre letters).
'nectarine' with its centre taken out is 'ne'.
'pierced'+'ne'='piercedne'
'piercedne' anagrammed gives 'perienced'.
'ex'+'perienced'='EXPERIENCED'
'and' is the link.
(Other definitions for experienced that I've seen before include "Underwent" , "Benefitting from previous actions" , "Practised and knowledgeable" , "Having much accumulated knowledge" , "Having wisdom gained through practice" .)
