Venture, hazard, risk, chance, jeopardize, endanger, imperil can all mean to expose to the chance of being unsuccessful, lost, or injured.
Venture implies a daring to stake something (as the success of an action or undertaking, one’s life, or one’s property) on the chance of getting an advantage or gain whether great or small; the term implies only the chances taken and the contingencies foreseen and does not, apart from the context, indicate its outcome.
But venture is often used in a weakened sense to mean little more than dare or, sometimes, attempt .
Hazard usually implies the putting of something to the chance of losing it; the term suggests more uncertainty or precariousness than venture and less hope of a favorable outcome and is often used in place of venture because of this implication.
Like venture , hazard is also often used in a much weaker sense but it comes closer to dare than to attempt .
Risk carries a still stronger implication of exposure to real dangers and of taking actual chances.
Chance may suggest a trusting to luck and a sometimes irresponsible disregarding of the risks involved in an action or procedure.
Jeopardize carries further the implication of exposure to dangers; it implies not only that they are a constant threat but that the odds in one’s favor are equally or even unfavorably balanced with those against one.
Endanger and imperil both stress exposure to dangers or perils, and do not in themselves throw emphasis upon a taking of chances. Imperil may imply more certainty or more imminence to the predicted risk than endanger but the two words are often used interchangeably without significant loss.
