IPA: /ˈdeɪndʒərəsnəs/
KK: /ˈdeɪndʒərəsnəs/
The condition of being likely to cause harm or injury.
The dangerousness of the situation made everyone feel uneasy.
Dangerousness → It is formed from "danger" (from Old French *dangier*, meaning to be able to harm or to put in peril) and the suffix "-ous" (meaning full of) combined with "-ness" (meaning the state or quality of). The word "dangerousness" refers to the quality of being full of danger or the state of being hazardous.
Think of 'danger' as the ability to cause harm, and when you add '-ous' for being full of and '-ness' for the state of, it helps you remember that 'dangerousness' means the state of being full of danger.
