A basket is a container made of woven straw or other material. You might keep your dirty clothes in a plastic laundry basket.
There are many different types of baskets, from the shopping basket you carry in a grocery store to the basket you aim for when you throw a basketball. There are figurative baskets, too, like the basket you add items to when you're shopping online. What's known about the origin of basket is that it comes from the Anglo-French bascat — beyond that, it's a mystery.
