New intern due to get contract (9)
I believe the answer is:
indenture
'contract' is the definition.
(indenture is a kind of contract)
'new intern due' is the wordplay.
'new' indicates an anagram.
'intern'+'due'='interndue'
'interndue' with letters rearranged gives 'INDENTURE'.
'to get' acts as a link.
(Other definitions for indenture that I've seen before include "Agreement binding apprentice to a master" , "Bind to service" , "Sealed agreement" , "contract" , "Document" .)
