Root Explanation

Dangerous → It is formed from "danger" (from Old French *dangier*, meaning to be able to harm or to put in peril) and "-ous" (meaning full of). The word "dangerous" means full of danger or likely to cause harm.

Memory Tip

Think of being 'full of' ('-ous') 'harm' or 'peril' ('danger') — that's why dangerous means likely to cause harm.
