There are some differences between British and American English. In grammar, for example, speakers of British English say "in hospital" and "Have you a pen?" Americans say "in the hospital" and "Do you have a pen?" Pronunciation is sometimes different. For example, when a learner is used to the British pronunciation [da:ns] (dance),he may not understand the American pronunciation [dzens]. There are differences betweenBritish and American English in spelling. For example, "travelled" and "honour" are British,"traveled" and "honor" are American. However, for the most part, British and American English are the same language.
