statutory
Required or created by an official government law.
Statutory means required or created by a written law passed by a government. When something is statutory, it exists because lawmakers officially wrote it into the rules that everyone must follow.
A statutory holiday is a day off that exists because the government passed a law declaring it, like Independence Day or Labor Day. Schools and government offices close on statutory holidays because the law requires it. A statutory requirement is something you must do because it's written into law, like wearing a seatbelt while driving or attending school until a certain age.
Think of the difference between your family's customs (like always having pancakes on Saturday) and actual laws (like stopping at red lights). Your family could change pancake day anytime, but changing a statutory rule requires the government to officially change the law.
You might hear about the statutory minimum wage, which is the lowest amount employers can legally pay workers, or statutory rights, which are protections the law guarantees to citizens. When something is statutory, there's paperwork, official votes, and legal language behind it. It's the law, established through official government action.
