British And American English (For The Non-Aborigines). Quite candidly, all you need to do is to choose and to decide (with conviction) on which form of English it is that you admire. Firstly, British English (BrE) is the form of English used in the United Kingdom. It includes all English dialects used in the United Kingdom. Secondly, American English (AmE) is the form of English used in the United States. It includes all English dialects used in the United States. They both differ, not too significantly (based on their lexicon), so it's best that one knows the former from the latter. Tar very much for the read! :)
