@thor England's English is rather odd. Some English people can speak intelligible English but others have some cursed dialect referred to as Cockney.
Can is short for canister. American English is from Shakespearean Era English and has preserved more of the old language. In the conversations I've had with people from England I noticed something unique. They tend to be verbose and dance around the information that could have been revealed with fewer words.
American English seems to include more words from different languages. The one thing that American English did was homogenize the different dialects of English so it would sound the same.
So Americans standardized English and borrowed words became common with the arrival of more Immigrants. We kept the language and it hasn't changed much since then. It's relatively simple for English and it was standardized before England's English. England's standard is referred to as RP or Received Pronunciation.
As for the rubbish bin, I will have to look that up. A bin is a container.
Rubbish might have come from Old French.
Trash might be Scandinavian.
Oddly they were introduced around the 1400s in English.
