Hazard, danger (4)
I believe the answer is:
risk
I believe this is a double definition.
'hazard' is the first definition.
(synonyms)
'danger' is the second definition.
(risk is a kind of danger)
(Other definitions for risk that I've seen before include "The possibility of danger - chance it" , "Jeopardy" , "Element of uncertainty" , "dangerous thing" , "Endanger, jeopardise" .)
