The willful burning of property, also known as arson, is a serious crime that can result in severe legal consequences. However, there are several synonyms that can be used to describe this act, including fire-raising, pyromania, and incendiarism. Fire-raising refers to the intentional setting of fires, while pyromania is a psychiatric disorder characterized by an obsession with fire. Incendiarism is a more formal term that refers to the act of setting fire to property with malicious intent. Regardless of the term used, the willful burning of property is a dangerous and devastating act that should always be taken seriously.
