Hi again and thanks! Is が wrong here or is を simply better? I learned that with たい sentences, where を is used, you can use が as well. What do you think?

Same question as above: Is が wrong here or is を simply better? が usage is sometimes challenging.

Understood and thanks! As before :) が is wrong or を is better?

Thanks again! Very helpful input :)

Is が wrong here or is を simply better? I learned that with たい sentences, where を is used, you can use が as well.

This is a direct sentence from Genki which is why I used it. In English, one can of course ask "what do you not want to do?" but it is rather limiting. Good to know that in Japanese it is limiting as well.

Thanks again. To be clear つもり is wrong here or has to be preceded by 住む to be clearer? I intended to say that Mary intends to be in Japan in 3 years. In English this works too - saying that she wants to live there and then saying that she will be there in 3 years time) as I previously stated that she wants to live in Japan so the following sentence "she plans to be there in 3 years" makes sense. Does this not makes sense in Japanese by using 住む in the previous sentence followed by いる in the next?

Thanks again, Mao! Great to have your input :)

If I want to use 弾く (to play) however, would 弾く as I used it be correct? In English, the difference is simply one of using "I want to learn piano" vs "I want to learn to play the piano". Both are correct, but I would like to express the latter: "I want to learn to play the piano".

To tell you the truth, I'm a little confused.
Sorry for the ambiguous answer, but in this case I think either would be acceptable.

In Japanese, "ピアノを習う" means that you want to learn how to play the piano. Therefore, to say "ピアノを弾くのを習う" sounds redundant.

Ah, so that's what you meant.
Then you can say "いるつもり"!

Did I answer all your questions?

Okay, great! I suppose that を simply sounds more natural, perhaps.

Got it.

Thanks!

Yes, thanks a lot, Mao!
