I’ve noticed many Americans using the term “gotten” and assumed it’s American English. Fine. But it’s not a word I would associate with good grammar on this side of the pond. Anyway, I’ve read a number of threads on here recently where the OP has written “gotten” in their original post (and each time I see it I shudder). Even worse…the dodgy verb crops up in this news article on the BBC (third para from end). The BBC (holds head in hands).

AIBU to despair at how this horrible little verb is infecting the English language…
