Menace or threat (6)
I believe the answer is:
hazard
I believe this clue is a double definition.
'menace' is the first definition.
(thesaurus)
'threat' is the second definition.
(thesaurus)
(Other definitions for hazard that I've seen before include "Potential danger" , "Jeopardy as on golf course" , "Obstruction feature on a golf course" , "Golf course obstacle" , "Possible source of danger" .)
