Concern to peril: how serious it sounds

Weight is what the five chips show, from soft to grave. Concern is soft and is what a manager might say about a delay. Risk is calm and measurable. Danger is clear and immediate. Menace adds something hostile or ongoing, like a pest or a reckless driver. Peril is grave and a little dramatic, so it suits stories and serious reports.

In a school essay on climate, a threat to coastal towns could be a risk (careful), a danger (direct) or a menace (emotional). Pick by how strongly your evidence supports the claim.

When the threat is spoken or written

If someone says they will cause harm, the noun is still threat, but you can be more exact. An ultimatum is a last demand: do this or else. Intimidation is a pattern of frightening behavior. Coercion is forcing someone to act by threats. Blackmail is a threat to reveal something unless paid. A warning is softer and can be friendly.

When a real threat has been made to you or someone close, plain words are best. Write down exactly what was said, when, and by whom, and report it to the right people.
