Although the British stopped using the past participle gotten about three hundred years ago, the American colonists and their descendants--especially in New England--still tend to use it.
Some English teachers have tried to ban its usage to make American English conform to British English, especially during the nineteenth and early twentieth century when there was a movement to purify English. Others are just not used to its use because it is not used in their region and hear it as an error.
Ultimately, language is convention. If you are writing for a formal audience outside of New England, you might want to use the simple past form got instead. It is like the dictum to never end a sentence with a preposition because that is something some people just will not put--ummm--up with which some people just will not put!
Yes.
For example: "Since I last saw you, you have gotten big!"
Gotten is correct, and very old. In England many people wrongly assume that gotten is a modern Americanism, but the truth is the English more-or-less stopped using it, and have forgotten (!) that they used to use it.
That said, "gotten" isn't good English. In most cases other, more precise and meaningful words should be used in its place.
While "have got" sounds wrong to American ears, "have gotten" can usually be replaced by "have become", and "have been able to" or "have had the chance/opportunity to" would make better sense in other situations.
"You would have got along with him" is proper English.
"On a train" is correct grammar.
Grammar.
The grammar is correct as it is.
No. The correct grammar is; "Yes, I have a girlfriend."
Can you end my day with correct grammar
No. Had gotten would be correct.
"Has gotten done" is the correct grammar. The auxiliary verb "has" indicates present perfect tense, which is appropriate when discussing completed actions that have relevance to the present moment.
No, correctly you would say you "wish you had gotten married".
It is correct in America in some contexts. In Britain, it is archaic ( and many speakers mistakenly think it is an Americanism ).
No, "will be had" is not a correct grammar. The correct grammar would be "will have."
"Gotten" is a past participle form that is more commonly used in American English. In British English, it is more common to use "got" as the past participle. Therefore, both "gotten done" and "got done" are grammatically correct, albeit in different variations of English.
"Gotten" is generally considered acceptable American English grammar, but in British English, "got" is typically preferred.
No, it is correct grammar, not a correct grammar.
The correct grammar is: "Are those correct?"
"On a train" is correct grammar.
The correct grammar for this sentence is: "When did you send it?"
No, the correct grammar would be "I hate you the way you hate me."
