British English is the original English, but these days it is not the normal way the majority of people from around the world communicate in English anymore. One of the many differences between British and American English is the pronunciation of the language. Also the vocabulary, and grammar structures used. American English grammar is the newer modern practical way of expressing yourself in English for casual, business, formal speech and writing. If you would like to learn the specific differences and or American English only, I am happy to teach you.
