Other forms: dangers
Danger is the nearness of something that could hurt you. In danger, out of danger, a danger to shipping, Danger — deep water.
It is both uncountable, meaning the state, and countable, meaning a particular threat: the dangers of the road. The prepositions matter: in danger of losing something is the standard pattern for a risk, and out of danger is what a hospital says when a patient is no longer critical. Note the adjective dangerous and the verb endanger — there is no verb to danger — and that danger money is extra pay for risky work.
1noundangerThe possibility of being harmed.
“There is no danger if you stay behind the barrier.”
2nouncauseSomething that could cause harm.
“That loose slab is a danger to everybody using the path.”
Too few real examples of this word to estimate which sense is commonest.
danger is a state of risk.
Old French dangier meant the power a lord had over you, from Latin dominium, lordship. To be in somebody's danger was to be in their power, and only later did the word come to mean physical risk. The oldest sense is about who can hurt you rather than what.
