American-British SpellingThere are many interesting differences between British and American spellings, some of which go back over 300 years. British spelling was standardised by the dictionary written by Samuel Johnson in 1755, taking into account the many European, especially French, origins of words. Noah Webster produced an American dictionary in the early 1800s, after the US had become independent of Britain, with the purpose of simplifying some of the complexities found in the British system and as a way of showing independence.Our latest set of worksheets take a look at some of these differences, just at a time when the American spellings are becoming more popular.Go to English Upper KS2 Sentences and Punctuation Standard English
