When do you use Wa and No

[chrisilang1092]

Hi I am just wondering how to use Wa and No. I don't know what they are called in Japanese grammar, but if JapanesePod101.com have it here for a tutorial, that would be nice.

Example, Watashiwa, Watashino, Bokuwa, Bokuno.

I just don't know when and what should you use in a sentence.

[ericf]

は (pronounced wa in this situation) is the sentence topic marker. の ( no ) is the possessive, used like apostrophe-s in English.

Aさん：これは、だれのりんごですか。
A san: kore wa, dare no ringo desuka.
Bさん：それは、わたしのりんごです。
B san: sore wa, watashi no ringo desu.
Aさん：りんごがすきですか。
A san: ringo ga suki desuka.
Bさん：わたしは、すきです。
B san: watashi wa, suki desu.

A: As for this apple, who's is it?
B: As for that apple, it's mine.
A: apples like?
B: As for me, like.

Does that make sense?

Cheers,
Eric.

As I understood, and i'm quite sure i'm right, they're both particles:

は tells you that the word before is the subject-argument;
の it's exactly like the Saxon Genitive ('s);
を wich tells you that tells you the object of the phrase!

About your examples:
私は・ぼくは means I (subject)
私の・ぼくの means My/mine
私を・ぼくを means Me (object form of 'I')

other examples:
スミスさんの国(くに)　Mr. Smith's homeland
田中さんの犬(いぬ) Tanaka's dog
