The key is not actually the letter that comes after a/an, it is the SOUND that comes after a/an. In this case you are saying 'just an "eff-why-eye,"' so the an should be used. In the same way, you do not get books at "an university bookstore," but rather a university bookstore.
Still not sure who decided things could qualify to be "an historical" event - in my head that sure sounds like it starts with a huh sound, not an ih sound.
In this case we would need to know the full sentence with the subject. For instance, if you say I have or I've...it would be correct to use gotten. However, although the sentence may be correct if you are using "have" in the sentence, the best way to say this sentence would be to eliminate have altogether. Then "gotten" would not be correct. You would say, "I just got back" or "We just got back". Usually when you are using have in the sentence (other than stating possession) than the use of "gotten" can be the correct usage for the word "got". In this sentence, since "back" is not something that is/was possessed, than gotten is the correct term if you are using "have" in the sentence. For example, if you were to say "we've gotten the answer", than that would be incorrect because it is showing possession. In this case you would want to say, "we've got the answer". There are many other rules pertaining to the use of gotten.
well it is correct but the grammar is wrong instead say "are you good at swimming" they both mean the same but this sentence a correct pronunciation.No. We say we are good at something if we mean that we do it well. The sentence "You are good in swimming" might be correct, but only if "swimming" is the name of a course of study, just as we might say "You are good in French," meaning you get get high marks in French class.
I have / I've just seen you do it. (so none of your variants).
I would say " I look forward to meeting you." instead of just " Look forward to meeting you." But as far as I am concerned it is just fine and I can be a grammar snob!
The colloquial phrase is "most probably" and in correct grammar is just "probably."
"July has just been started" is not correct grammar, instead the correct grammar is "July has just started."
It would be better to add "have." The concert to which you have just listened was the same one you once heard as a child.
The sentence "I got here just 2 minutes before their cut off time" is correct grammar.
The correct grammar would include an introduction, not just an object. A better sentence would be "This is the first selfie I've taken with this Air-Phil Jersey."
Yes, your grammar is correct. Your sentence "Just take care on your way home" is a polite way to tell someone to be safe while going home.
The sentence is incorrect as it lacks the proper punctuation. A better sentence would be "I spent less today and I'm happy I was able to save money, even just for one day".

No, this is not correct grammar. I'm not even certain what you mean to say. Perhaps you could say "I thought my email was sent to you. I'm sending it again just in case." Or you might say "I thought I sent that email to you. Did you get it or not?"
The correct grammar is YOU AND I if used as a subject, e.g. ""You & I will have a jolly good time". Correct grammar requires YOU AND ME if used as an object, e.g. "This is just between you and me" "I" designates a subject and "me" designates an object.
No, just leave out the "with". 'He resembles his father.' would be correct.
Both are correct. Most people use the latter.
Yes. "The car that just passed was theirs" is grammatically correct.
