Stops me going in for changes (6)
I believe the answer is:
emends
'changes' is the definition.
(I've seen this before)
'stops me going in' is the wordplay.
'stops' becomes 'ends' ('end' can be a synonym of 'stop').
'going in' is an insertion indicator.
'ends' going around 'me' is 'EMENDS'.
'for' acts as a link.
(Other definitions for emends that I've seen before include "Alters written material to remove errors" , "Corrects and improves the text" , "Changes" , "Send me (anag.); corrects" , "Makes corrections in written material" .)
