Give away and Japanese quizz.

One only does what one wants.

Agreed. I got the first four. I think I know the last three as well, but none of the ways I've tried to express it have worked.

Indeed. I'm reasonably certain I know what each item means (I have a B.A. in Japanese Studies), but it's taking ages figuring out (i.e. guessing) what particular turn of phrase is wanted.
(Although, to be fair, the fact that English isn't my first language probably isn't helping ^^)

You are thinking too much. Or too little. I did not use a dictionary for any of this, really, but I am quite confident in my Japanese skills. Also, I ran everything by a dictionary as well, so it is correct.

orr.. I don't get 5 and 7

The number of stars is not in any way or form related to the number of letters in the missing area.

Not really easier - it confirms I knew the right answer, but I still can't figure out the needed answer format :/

yeah, google translate isn't very reliable in this case ;X~

I'm stuck on 5 and 7 as well. My Google-fu isn't good enough!

Q#6 is just the reading of the one of the parts of the sentence that is wrong.

Q#7 is following the format shown. What do you think it is?

Yes. You can see it! GZ! Or you copy pasted, so I cant help you.

After 2 days everyone had a fair chance figuring out the answers by themselves, so feel free to share your answers.
I can't solve no.5 - tried out nearly everything I can think of and looked up words on a thesaurus.. still think "oneself" would fit best.
And I can't solve no.7 - they have in common that you can use them to adress a second person and that it's considered quite rude to use them nowadays. Maybe the first ** is "polite".

One reprset one word, one represent two. Which is which I wonder...

^this.
No offense NoobsDeSroobs, but IMOH, language puzzles should be about figuring out, well, puzzling aspects of language, not guessing which exact answer format or phrase out of a million possibilities the puzzle's author had in mind when he made it.
