Judge going back on short stretch for hunter (8)
I believe the answer is:
ferreter
'for hunter' is the definition.
(I've seen this before)
'judge going back on short stretch' is the wordplay.
'judge' becomes 'ref' (referee).
'going back' is a reversal indicator.
'on' becomes 're' ('on' can be mean 'with reference to').
'short stretch' becomes 'ter' (I can't explain this - if you can you should give a lot more credence to this answer).
'ref' reversed gives 'fer'.
'fer'+'re'+'ter'='FERRETER'
Can you help me to learn more?
(Another definition for ferreter that I've seen is " Hunter".)
