Where did you start or the best techniques for learning Polish. [85]
Mafketis will know better, but as far as I understand, American English is much closer to the English spoken in the 18th century UK
Not sure about that, but standards in the UK seem to revolve around southern England and British Isles influence in the US is much more from Scotland, Ireland and Northern England. There's also German influence absent in the UK, not to mention AAVE (a major influence on colloquial language).
Interestingly, most americans have no idea how British people really speak (both in terms of range of accents and idioms, colloquial usage etc). There's a kind of fake British dialect common in the media that Americans mistake for the real thing (think Stewie on Family Guy). I know it used to come as a very big shock to Americans arriving in Poland and meeting British people to hear them speak.
