Take from or put into the amended text (6)
I believe the answer is:
extort
'take' is the definition.
(extorting is a kind of taking)
'or put into the amended text' is the wordplay.
'put into' is an insertion indicator.
'the amended' indicates an anagram.
'text' is an anagram of 'extt'.
'or' inserted into 'extt' is 'EXTORT'.
'from' is the link.
(Other definitions for extort that I've seen before include "Wring (money) out (by violence, etc)" , "Secure money by intimidation" , "Get by force" , "Get by intimidation" , "fleece" .)
