Oxford English Dictionary This link opens in a new windowOxford English Dictionary (OED Online) - This database covers words from across the English-speaking world, offers the best in etymological analysis, lists variant spellings, and it shows pronunciation using the International Phonetic Alphabet. As a historical dictionary, the OED is very different from Dictionaries of current English, in which the focus is on present-day meanings. You’ll still find present-day meanings 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 film scripts and cookery books.
