Etymology
Origin of arsonist
Explanation
An arsonist is someone who deliberately sets houses on fire. Investigators who find empty gas cans near the scene of a blaze tend to suspect an arsonist is responsible. Arsonists destroy property by burning it; that can mean setting fire to buildings, boats, cars, or forested land. An arsonist's motives can include collecting insurance money after burning their own property — or violent revenge, by burning someone else's. The crime they're committing is arson, which is usually a felony because it's so destructive and dangerous. The Latin root of arsonist means "to burn."
