Men head off wild animal for hunter (5)
I believe the answer is:
orion
'hunter' is the definition.
(I've seen this before)
'men head off wild animal' is the wordplay.
'men' becomes 'or' (I've seen this in other clues).
'head off' means to remove the first letter.
'wild animal' becomes 'lion'.
'lion' with its initial letter removed is 'ion'.
'or'+'ion'='ORION'
'for' is the link.
(Other definitions for orion that I've seen before include "Great hunter of Greek myth, and a constellation" , "Constellation that includes Betelgeuse" , "One who would hunt" , "Group of stars" , "Bright constellation, named after legendary Greek hunter" .)
