Have you ever wondered, “What kind of thing is that?” I use Wikipedia to answer that question all the time. You can even use Wikipedia to find similar things that share the same category. What kind of thing is a senate? Well, apparently it’s a legislature. Did you know that a tricameral legislature is also a kind of legislature, and that there was a Tricameral Parliament in South Africa until 1994? You could spend all day exploring the order of things.
