HE Oxford English Dictionary is the accepted authority on the evolution of the English language since the twelfth century. It traces the origin, history and meaning of more than half a million words and contains 2.5 million quotations to illustrate the usage of these words.
The OED covers words from across the English-speaking world, from North America to South Africa, from Australia and New Zealand to the Caribbean. It offers the best etymological analysis and listing of variant spellings, and each entry shows pronunciation using the International Phonetic Alphabet.
The OED is a living document that has evolved since the mid-19th century. It will continue to reflect the evolution of the English language well into the future.
