Sentence Structure
 

Ok i was wondering how do i say that girl is pretty. In japanese as a translation/ I am confused. I got

Kono onnanoko wa kireina desu. Is that rite?

その・あの女の子はきれいです。
Sono/Ano Onnanoko wa Kirei desu.

Use Sono if the listener doesn't know the girl. Use Ano if the speaker knows the girl as well.

thanx
 

Thanx so much for the help.

Your sentence is essentially correct, but no one in Japan really speaks that way. The simple/common way to say it would be to look in the direction of the girl and use "kirei-na...".

I would just say

sono kanajo (onna no ko) wa kirei na

You could also simply say...onnanoko kirei na

And the listener would know what/who you're talking about.....Since it's not rocket science, you know?

It depends on the context. And as for the previous 3 posters, neither one of you got it right. It all sounds awkward.

Um...hate to tell you buddy but "onna/onnanoko kirei na (na is optional)" is a perfectly common and casual Japanese sentence.

I think some of you are mixing up きれいな（人）and きれいなぁ

The first NA is used when きれい is placed before a noun. The second is a more colloquial phrase, more common in Kansai, but basically has country-wide usage and is used the same way as ね.

So きれいねぇ～　and きれいなぁ～ have the exact same meaning, but different people would use one or the other.

"Onna kirei na" sounds like something a monkey or 1960's robot would say.
