Both Argentine and Argentinian are correct, but I think that Argentinian is more commonly used (at least in American English).

This is a really interesting question and I hope a few other people offer their thoughts, because I'm not 100% confident in my answer. That said, I believe that #2 is correct. In both versions you correctly use the conditional for the first phrase. However, I don't think the conditional is needed for the second phrase. Imagine if it were rephrased as follows: "She is telling you that I will talk to her when I see here the day after tomorrow, but she's wrong." There's nothing conditional here. Even though she's incorrect, she has, in fact, stated that she will talk to you when she sees you the day after tomorrow. Anyone else have thoughts on this one?

I think that you can use them interchangeably. They are both, obviously, convey that you think the food is great. They both are somewhat colloquial, but avoid using slang.

I think the easiest way to think about this is that "await" means "wait for" or "waiting for" For example: "I am waiting for your response" has the same general meaning as "I await your response." That said, the version that uses "await" sounds more formal and, perhaps, more polite.

Okay. First, at least in American English, we'd be MUCH more likely to use "intersection" than "crossroads." Outside of old blues songs (who doesn't love Robert Johnson!) I've never heard an American say "crossroads" in this context. It's not incorrect, it would just be unusual. Perhaps "crossroads" is more commonly used in British English (can any Brits comment on that?). With that out of the way, if I were to use "crossroads", I would say "There was an accident at the crossroads this morning." I can't identify why, but "an accident in the crossroads" sounds terribly unnatural to my ear. I Using "intersection" instead, I think it becomes a bit tricky. If the accident occurred right in the middle of the intersection, then I would likely say "there was an accident in the intersection this morning." Otherwise I would probably say "there was an accident at the intersection." I think this would be pretty fine distinction, though, and I don't think that either word choice sounds unnatural.

Hi Irina, Is "Crossroads" the name of a place, like a restaurant (as implied by the capital "C"), or do you mean an intersection of two roads? -Jeff

Referring to a patient, I think that the British would say "he's still in hospital" while Americans would say "he's still in the hospital." In general, I think it would be most common to say that a person is "in the hospital" if they are staying there as an inpatient, and most common to say "at the hospital" if they are an outpatient, visitor, or someone who works at the hospital. Having said that, you would be understood if you said "Bob is in the hospital visiting Mary" (though "Bob is at the hospital visiting Mary" sounds far more natural to me). .

1) "I've probably sat in this chair for one hour" is correct. However, I think it would sound more natural to say "an hour", instead of "one hour." For the phrase regarding Jesus, it depends on whether you are aiming to say this in modern conversational English, or in Biblical English. I believe the bible (depending on the exact translation) says something like "Jesus is seated at the right hand of God." That would be an unnatural way to say this in modern conversational English. If you were talking about your friends Bob and Mary, you would likely say that "Bob is sitting to the right of Mary" or "Bob is sitting on Mary's right hand side" Why use "right-hand" instead of "right?" I can't give a formal linguistic explanation. I can only tell you that when referring to a person's left or right side, people commonly say right-hand or left-hand. However, there would be nothing wrong with saying "Bob is sitting on Mary's right side." It would be correct and understood, and it would also sound natural. I think it would be a less common construction, though. 2) First, I'll say that I'm not a gamer. So there are probably phrases that gamers use that I don't know. Having said that, I think that "I played version 1.3 of this game at the moderate level for the first time" would be the correct construction. Hopefully, a gamer will join the thread to help out with this one.
