The main differences between British English and American English are pronunciation, spelling and lexicon. However, syntax is not a big difference. Now we are going to have a glimpse at each, illustrating them with some examples.
Referring to pronunciation we can settle some basic parameters to see the difference between dialects. First we have the merger of [I] and [å] before nasal consonants, makes pin and pen homophones in the American dialect.
