Why “malefacture” is a great word
MALEFACTURE — [Noun] The act or process of committing an evil deed or causing harm. From the Latin malefactūrus ("about to do evil"), future active participle of malefaciō ("to do evil or harm"), from male ("badly, ill") + faciō ("to do, make"), with the English noun-forming suffix -ure. First attested in English c. 1635–1652. Unlike "malefaction," which denotes the evil deed itself, or "malfeasance," which confines itself to official misconduct, malefacture is the very process of evil's making. It is the poisoner's careful distillation, the lie woven into a legal contract, the cold architecture of a betrayal—a terrible workmanship where evil is not a static fact but a deliberate construction, a future sorrow built brick by bitter brick.
