To imperil someone or something is to put them in danger — to make harm more likely. The storm imperiled the boats. A careless lie can imperil a friendship. It is a serious, slightly old writing verb. News still likes it; at the table people say put at risk, endanger, or threaten. The object is the one now in danger (you imperil the boats, not the storm). Though actually, it has a stern feel, as if the danger is real and close, not a small worry. You will not hear it much in casual talk, and that is fine: endanger does the same job in simpler clothes.
危及
