51 American and British English
These two varieties of English are very similar. There are a few differences of grammar and spelling, and rather more differences of vocabulary and idiom. Modem British English is heavily influenced by American English, so some contrasts are disappearing. Pronunciation is sometimes very different, but most American and British speakers can understand each other easily.
1 grammar
Here are examples of the most important differences. In many cases, two different forms are possible in one variety of English, while only one of the forms is possible or normal in the other variety.
American English
