Went in for tree chopping in the end (7)
I believe the answer is:
entered
'went in' is the definition.
('enter' can be a synonym of 'go in')
'tree chopping in the end' is the wordplay.
'chopping' indicates an anagram (I've seen 'chopped' mean this (letters chopped or smashed up)).
'in' indicates putting letters inside.
'tree' with letters rearranged gives 'tere'.
'tere' inserted within 'end' is 'ENTERED'.
'for' is the link.
(Other definitions for entered that I've seen before include "Put down" , "Ten deer (anag) - went in" , "Enrolled or went in" , "Logged; arrived" , "Came in; recorded" .)
