Golf supporter hires old character to produce choppers (6)
I believe the answer is:
teethe
'produce choppers' is the definition.
(to teethe is to develop teeth or 'choppers')
'golf supporter hires old character' is the wordplay.
'golf supporter' becomes 'tee' (support for a golf ball).
'hires' is an insertion indicator (inserted letters are hired or acquired).
'old character' becomes 'eth' (letter of the alphabet in Old English).
'tee' placed around 'eth' is 'TEETHE'.
'to' is the link.
(Other definitions for teethe that I've seen before include "Cut one's milk teeth" , "Grow gnashers!" , "Cut champers" , "Have initial trouble (as a baby?)" , "Experience growing pains" .)
