Image of logo for the Oxford English DictionaryThe Oxford English Dictionary (OED) records the development of the English language over the last 1500 years. It traces the evolution of over 600,000 words through 2.5 million quotations from a wide range of sources—from classic literature and specialist periodicals to film scripts, wills, and cookery books.

As a historical dictionary, the OED is an unrivalled guide to the meaning, history, usage, and pronunciation of English words, both past and present. It records new words and the changing usage of existing words.
