Old plastic pierced the skin of nectarine and went through (11)
I believe the answer is:
experienced
'went through' is the definition.
(experiencing is a kind of going through)
'old plastic pierced the skin of nectarine' is the wordplay.
'old' becomes 'ex' (prefix meaning former or onetime).
'plastic' indicates an anagram (plastic can mean easily moulded).
'the skin of' suggests removing the centre.
'nectarine' with its middle removed 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" .)
