Ones that I'm aware of include:
- British English (as used by EL&U itself!). I don't view this term as ideal, as I'm referring to differences between English in commonwealth countries and the USA, rather than differences between Australia and the UK, for example.
- Queen's English. Not ideal, because it also suggests a very refined, as opposed to colloquial, form of English.
I'm aware that American English isn't just spoken in the USA, but maybe I don't mind that term as much, as I think those countries are often ones where it's spoken as a second language, such as Japan.
