A million is 1,000,000. It's a large number made of a thousand thousands. If you have a million dollars, you’re a millionaire!
The word million comes from the Italian milione, which literally means "a great thousand.” It’s great to have a thousand, but it’s awesome to have a million! A million is a big number but not so big that you don't see it used frequently. In fact, being a millionaire isn’t even a big deal anymore. An online video might be watched by a million viewers, and there are millions of people in big cities like New York City and Chicago.
