A corporation is a type of business organization that the law treats as its own separate entity, almost like an artificial person. When people create a corporation, they file special paperwork with the government that gives their business its own legal identity, separate from the people who own or run it.

This might sound strange, but it's incredibly useful. If you and your friends start a lemonade stand, you're personally responsible for everything that happens. But if a corporation's business fails or gets sued, the owners (called shareholders) usually don't lose their personal money or possessions beyond what they invested in the company. This protection, called limited liability, made people much more willing to invest in new businesses and take entrepreneurial risks.

Corporations can own property, sign contracts, and even sue or be sued in court, all under the corporation's name rather than the owners' names. They continue existing even when ownership changes hands. If you buy shares in a corporation, you own a tiny piece of it, but you're not personally running it or responsible for its debts.

Most large businesses you know are corporations: car manufacturers, technology companies, restaurant chains, and sports teams. Forming a corporation involves serious paperwork and following strict rules, but that structure has helped build many of the world's most successful businesses.
