How to Use Japanese Particles

"YUU ASAKURA: Now, I'm going to talk a little bit about particles. In English, it's rare that you need such words to add some new meanings, but in Japanese it's very crucial. And I'm going to introduce the most important particles, three of them. And the first two, we've been using these for a while. The first one is "wa," and actually, this is to make a subject. We have the noun here. It could be I, you, could be somebody's name, could be this, that. And then we had this particle "wa" following "the," and it will make a subject. We also have the particle "ga," to make a subject. The difference is you emphasize the subject with "ga." To your friends, "watashi wa isogashi desu" or "watashi ga isogashi desu" is I am busy and I am busy. So it's how you want to say it. It makes a difference. And this one is "no," and the meaning of it is "of." This is how to use it. So "watashi" is I, right? And let's say I want to say my book. So in English, "I" changes to "my." In Japanese, you put "no" after "watashi." And the book is "hon" in Japanese. And so it goes "watashi no hon." It means "my book." So if it's your car - car is "kuruma" - it goes "anata no kuruma.""
