Американский словарь английского языка

Language, in which the spelling of many words was simplified with the aim of making American English more logical in its reading and pronunciation.
British English adopted Samuel Johnson’s Dictionary of the English Language of 1755 and thus retained many original spellings from words borrowed into the language. English contains a vast number of words of French origin, the spellings of which are often convoluted and contain additional (arguably superfluous) letters that are not pronounced. American tends to simply words of this kind, where British has left them unchanged.
