College to steer away from resin (9)
I believe the answer is:
polyester
'resin' is the definition.
(I know that polyester is a type of synthetic resin)
'college to steer away' is the wordplay.
'college' becomes 'poly' (polytechnic).
'to' means one lot of letters go next to another.
'away' indicates an anagram (letters move away from their original places).
'steer' with letters rearranged gives 'ester'.
'poly'+'ester'='POLYESTER'
'from' acts as a link.
(Other definitions for polyester that I've seen before include "material found in fabrics" , "Man-made fibre" , "Textile material" , "Stole prey (anag) - synthetic material" , "Synthetic compound" .)
