Oxford English Dictionary
Browse or search over 600,000 words showing meanings, history, and pronunciations from across the English-speaking world. As a historical dictionary, the OED is very different from those of current English, in which the focus is on present-day meanings. You'll still find these in the OED, but you'll also find the history of individual words, and of the language—traced through 3 million quotations, from classic literature and specialist periodicals to films scripts and cookery books. You can also explore a timeline of when words entered the English language and the many works that have act as sources for the OED.
