Regardless of the vocabulary, the spellings, the punctuation marks, or the accents, as an American English speaker, I mostly understand what people from the United Kingdom, Canada, Australia, and New Zealand are saying without any difficulties. I can also understand what fellow Americans from the East Coast through the West Coast are saying as well. However, in most languages, it is a different story. Spanish is a good example where speakers from different parts of the world had problems understanding each other. With many regional and national dialects found in the English language, why do most English speakers have no serious problems understanding each other compared to other languages?
