Menacing → It is formed from "menace" (from Old French *menace*, meaning threat) and the suffix "-ing" (indicating the action or process). The word "menacing" describes the action of threatening or presenting a danger.
Think of a 'threat' ('menace') that is actively happening ('-ing') — that's why menacing means to be in the act of threatening.
