Related Words

Danger, hazard, peril, jeopardy imply harm that one may encounter. Danger is the general word for liability to all kinds of injury or evil consequences, either near at hand and certain, or remote and doubtful: to be in danger of being killed. Hazard suggests a danger that one can foresee but cannot avoid: A mountain climber is exposed to many hazards. Peril usually denotes great and imminent danger: The passengers on the disabled ship were in great peril. Jeopardy, a less common word, has essentially the same meaning as peril, but emphasizes exposure to the chances of a situation: To save his friend he put his life in jeopardy.

Etymology

Origin of danger

First recorded in 1175–1225; Middle English da(u)nger, from Anglo-French, Old French dangier, alteration of dongier (by influence of dam damage ), from Vulgar Latin domniārium (unrecorded), equivalent to Latin domini(um) dominion + -ārium (neuter of -ārius -ary )

Explanation

When you're in danger, it seems likely that you might get hurt. Your mom might warn you that if you don't wear your bicycle helmet, you're in danger of getting injured. A baby bird teetering on the edge of its nest is in danger, and a driver whose car stalls on railroad tracks is also in danger. When something unpleasant might happen, you can also use the word danger: "We were in danger of running out of guacamole before the party ended." Danger can also be a precarious or perilous place, as when you step up on the curb on a busy street, out of danger.
