Absolutely.

No. Okay. Not at all. I mean, regular languages are too simple for human languages. It's a part of the hierarchy, but human languages in the phrase structure world are at least context-free, maybe a little bit more, a little bit harder than that. So there's something called context-sensitive as well, where you can have, like this is just the formal language description,

In a context-free grammar, you have one... This is like a bunch of formal language theory we're doing here.

Okay. So you have a left-hand side category, and you're expanding to anything on the right. That's a context-free. The idea is that that category on the left expands in independent of context to those things, whatever they are on the right. It doesn't matter what. And a context-sensitive... says, okay, I actually have more than one thing on the left.

And a context-sensitive... says, okay, I actually have more than one thing on the left.

I can tell you only in this context, you know, maybe you have like a left and a right context or just a left context or a right context. I have two or more stuff on the left tells you how to expand those things in that way. Okay, so it's context sensitive. A regular language is just more constrained. And so it It doesn't allow anything on the right.

It allows very... Basically, it's one very complicated rule is kind of what a regular language is. And so it doesn't have any... I was going to say long-distance dependencies. It doesn't allow recursion, for instance. There's no recursion. Yeah, recursion is where you... Human languages have recursion. They have embedding.

And you can't... Well, it doesn't allow center-embedded recursion, which human languages have, which is what... Center-embedded recursion.

Yeah, within a sentence. So here we're going to get to that. But the formal language stuff is a little aside. Chomsky wasn't proposing it for human languages even. He was just pointing out that human languages are context-free. Because that was kind of stuff we did for formal languages. And what he was most interested in was
