Don’t confuse “capitol” and “capital.”
A “capitol” is a building where a state’s or country’s government meets: The officials gathered in the capitol. The noun “capital” has several meanings. A capital may be the city that contains the capitol: Pierre is the capital of South Dakota. It can refer to wealth: She will need a lot of capital to start her own business. It can mean an upper-case letter: Always use a capital at the beginning of a sentence. And finally, it can refer to the main or most famous city in a certain respect: Philadelphia is sometimes called the cheesesteak capital of the world.
If you get mixed up, just remember that “capitol” only means a government building. For every other usage, “capital” is the correct word.
