Whip - it's possibly used in hunting (8)
I believe the answer is:
chastise
'whip' is the definition.
(thesaurus)
'it's possibly used in hunting' is the wordplay.
'possibly' is an anagram indicator.
'used in' indicates putting letters inside.
'hunting' becomes 'chase'.
'its' anagrammed gives 'tis'.
'tis' put within 'chase' is 'CHASTISE'.
(Other definitions for chastise that I've seen before include "Correct!" , "Castigate or punish" , "Berate" , "Censure severely" , "discipline" .)
