That's true, though I have noticed that quite a lot of younger British speakers are using "gotten" as the past participle. It was common usage in England in the 17th century, and probably after that.I am not a teacher,
In BE one goes with 'got' whereas in AE one uses 'gotten'.
Are both "got" and "gotten" the past participle of the verb "to get" ?
If so, can they both be used in the same context ?
