yet >> already
?

I think it's OK for interrogative sentences.

I would say the word "yet" would be more suitable for the following sentence:
Haven't you finished yet?

@Dima, as for yourself, you used in your variant the same word I would use in Hebrew in such context, i.e., уже, rather than еще.

It's interesting to note that most of the contributors in the languages of the current thread have used their own counterparts of "already" rather than "yet":
French: déjà
Polish: już (same as Russian, уже)
Spanish: Ya
Portuguese: Já
etc.

Actually, I translated this phrase from Japanese :-) Japanese もう　(mo:) means "уже" here. As for English, I saw such kinds of English sentences before and my dictionary suggests to translate "yet" as "уже" in interrogatives.
And as for "Haven't you finished yet?" it will be translated something like "Ты (что, ) всё еще не закончил?" or "Ты (что, ) до сих пор не закончил?", I believe. :-)

Yes, I agree.
By the way, is this "mo" part of the phrase "mou ichido kudasai"? :-)

That's right! :-) もう一度ください（mo: ichido kudasai) literary means "еще раз, пожалуйста". That is, "mo:" can mean "еще" sometimes. :-)
By the way, is we compare Russian "Ты уже закончил?" and "Ты еще не закончил?" we'll found that those two sentences are very similar in sense. :-)

Thanks! :)

By the way, I'm not really sure "Ты уже закончил?" and "Ты еще не закончил?" are similar in their meaning. It depends on the real situation (the situation on the ground), I guess :)

Yes, you're right. :-) All depends on the real situation. But I think it just illustrates one more time how close to each other "еще" and "уже" are and we are just lucky that in Russian, unlike some other languages, it's almost impossible to confuse them with one another. :-)

@CK, could you comment on this sentence?

I believe the normal way to say it in English nowadays would be with "already". However, you are a native speaker, so, what would you think of "yet" in the current sentence? Does it sound OK?

Thanks a lot, CK.

So, for your native speaker's ear it sounds the same as "Have you finished already?"
?
Or is there a different shade of meaning here?

>> Google with the complete sentence in quotes.
But beware if the Google says the results are approximate (e.g. like with your queries, ‘Результатов: примерно 120 000’): these numbers are good for nothing and shouldn’t be trusted.

Thanks, @CK (yes, I would use "already" "inside" the sentence rather than at the end, same as you).

Google's gone downhill over the last few years.

"When we use yet in an affirmative question, it shows that the speaker is expecting something to happen"

"We use already to emphasise that something was completed before something else happened." "Already is also used to show surprise about things that have happened or will have happened earlier than we expected."
