I just got back, or I just returned would be better.
This is grammatically wrong. But it's lyrics, so just let it be. Actually, the grammar of verse may be different from the grammar of prose. In this sentence, the relative pronoun "who" is understood.
no, Kevin Jonas is now engaged though. You must have gotten then names wrong from a source or just thought the wrong person
no it's not wrong but just think about how she feels or he feels. maybe if you two were both in on it like angry sex or something.! ya know!?
It will cool down, nothing is wrong with it. It is just air.
It sounds like she may have something wrong with her. I would take her to the vets just in case.
"July has just been started" is not correct grammar, instead the correct grammar is "July has just started."
It can be normal, if that's the way the woman feels. Its not wrong, just unusual
Grammar just difficult if it will be asked to perform or say on-the-spot correctly. Unlike if it is written, you have a time to analyze it if it is wrong or not. Just read. Try to understand. And analyze.
True, because most people just upload incorrect information - which then others believe. I have seen horrific spelling, and the grammar... There just aren't words to describe it.
All languages have grammar.
He may have just realized what he did was wrong or he may not have received the response he wanted from you and feels foolish.
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.
