- [Voiceover] Hi, everyone.
My name is David, and I'm here to introduce you to Grammar on Khan Academy.
Welcome.
I'm so glad you could join me.
So, let's start by asking the question,
"What is grammar"?
What is this thing, why is it worthwhile to study it, why would you wanna put up with listening to me?
Well, first of all, grammar is a set of conventions and rules that govern language.
So what's the difference between a convention and a rule?
Well, a rule is kind of the bare minimum of what it takes to make your language understandable by other people, right?
