Danger.
Synonyms:
hazard, insecurity, jeopardy, peril, risk.
Danger is exposure to possible evil, which may be either near and probable or remote and doubtful; peril is exposure to imminent and sharply threatening evil, especially to such as results from violence. An invalid may be in danger of consumption; a disarmed soldier is in peril of death. Jeopardy is nearly the same as peril, but involves, like risk, more of the element of chance or uncertainty; a man tried upon a capital charge is said to be put in jeopardy of life. Insecurity is a feeble word, but exceedingly broad, applying to the placing of a dish, or the possibilities of a life, a fortune, or a government. Compare HAZARD.
