Root Explanation

Endanger → It is formed from "en-" (meaning to cause to be in) and "danger" (from Old French *dangier*, meaning to put in a position of risk). The word "endanger" means to cause someone or something to be in a state of risk or peril.

Memory Tip

Think of being 'caused to be in' ('en-') a 'risky situation' ('danger') — that's why endanger means to put someone or something at risk.
