Thnx sam. I gave you san'en. 4& 5 were a little off though.

4. kono manga wa ikura desu ka?     you used kore in place of kono. remember kono modifies a noun (in this case manga) while kore takes the place of a noun.

5. kono suteki na mahou no kutsu wa takai desu.   you used matsu instead of kutsu. so technically it was an allright grammatical sentence but instead of saying "these wonderful magic shoes" you said "This wondeful magic pine tree".

Ja! Jugyou hajimemasu!!

The time has come. We've been using them a bit all ready, but we haven't explored their functions exhaustively. The time is now! I give you... KONG!! Eh.. er.. I mean ADJECTIVES!!

Dialogue.

Yukie chan wa kirei da na.   Isn't Yukie pretty.

so ne. sara ni, yankumi toshite kirei na kimono o kiru.   Yeah, and moreover, as Yankumi she wears beautiful kimono.

demo, yakuza nanka chotto kowai ne.  But, yakuza and all is a little scary isn't it.

so ka mo kedo, yankumi wa kowai hito ja nai yo. That maybe so, but yankumi isn't a scary person.

notes

sarani   moreover, in addition, further more

...toshite  as...    I as a teacher watashi wa kyoushi toshite, or He as a foreigner kare wa gaikokujin toshite, etc.

kiru   wear

nanka   this is hard to translate. The preceding word and all like things. Don't worry too much about it. It changes the nuance more than the meaning so if you read the sentence without it it still makes sense.

chotto   a bit, a little

ka mo   maybe. Short for ka mo shirenai.

kedo   but. This occurs at the end of a sentence fragment as opposed to demo, which would occur at the beginning of a sentence.

hito   person

ja nai   isn't. This is the negative form of da. To make these polite, da turns into desu and ja nai turns into de wa arimasen or ja arimasen.

Ok there are four ways to modify a noun in Japanese.(four ways I can think of right now)

1. -i type adjectives.

    These are any adjective that ends in -ai, -ii, -ui, or -oi. (note it DOES NOT include -ei ending adjectives)

These adjectives can appear right before a noun without any modification.

takai hon expensive book, kawaii koneko cute kitty, ookii kuchi big mouth, warui hito bad person, kodomoppoi otoko childish man.

2. na type adjectives

   These are all the other adjectives. When these adjectives come before a noun na has to be put in between the adjective and the noun.

fukuzatsu na hon complicated book, jouhin na onna elegant woman

3. other nouns

when another noun is used to modify the main noun it's connected with no.

mahou no kutsu magic shoes (lit. shoes of magic). yankumi no seito yankumi's student (lit. student of yankumi). tomodachi no natsumi my friend, natsumi.

I'd like you to be aware of this but don't over worry about it. nouns modifying nouns can get complicated (fukuzatsu).

4. verb phrases

don't over worry about it now. But like how we add to a noun with verbs after it (the guy swimming) verbs can come before nouns and modify them in Japanese (oyondeiru yatsu)
