Oxford English Dictionary
The Oxford English Dictionary provides an unsurpassed guide to the English language, documenting 600,000 words through 3.5 million illustrative quotations from over 1,000 years of history across the English-speaking world.
As the world’s foremost historical dictionary of English, the OED’s ongoing mission is to capture the development of all words – past and present – from the moment they enter the language to their most recent usage, subtly adjusting our image of the English language with each update.
