I have never seen before うるさい　(urusai) written in kanji. To tell the truth I have never known that the kanjis for that word even exist :)

Don't worry. No one writes うるさい in kanji.

That's why I'm always using this online dictionary (www.jisho.org), because there are always notes, whether the word is commonly used, or whether it's usually written in kana. I recommend it to all Japanese learners.

Thanks. Maybe I should use that site, too. LOL I like your new signature, by the way.

Lmao! Sig'd

Edit:

Hang on, are you sure that means noisy??? I just checked it in two dictionaries and the meaning seems to have more to do with rape and incest than it does noise level....

from saig-jp.com:
deceive
wicked
evil
vicious
dirty
lewd

And then look at the examples... Japanese Kanji Dictionary

I don't know why, but two days ago a kanji caught my attention, which I only knew written in hiragana. Somehow I like it, don't know why. ^^

多分　(tabun, maybe)

Edit: My boyfriend said 姦 has the meaning like "rape". So, Amnell, you are right. ^^b

I found it translated "also as noisy" in a book I have and in rikaichan...
Any word on this from Japan?

If you check the examples on the dictionary I linked to, the last example is

cackling (noisy,clamorous) women

However, that is the only example I've yet seen having to do with noise. I have a program called Wakan that basically compiled four online dictionaries into one database and it had no definitions that had to do with noisy.

What I find funny is that the kunyomi is かしましい, which sounds a lot like an Anime I watched a while ago called Kasimasi, which did have to do with a group of energetic girls....

姦しい is an adjective meaing nosy in a lively way...just like when you put 3 women togetehr!

But if you're asking if we actually use that word 'kashimashii' or the kanji in our daily lives here in Japan, then my answer will be no. Only older people (probably over 60) would use it. It's a very nice old word but it's not easy for a 5-syllable word to survive when it doesn't have a more broad meaning.
