Oxford English Dictionary.
The OED presents the words that have formed the English vocabulary from the time of the earliest records down to the present day, with all the relevant facts concerning their form, sense-history, pronunciation, and etymology. It embraces not only the standard language of literature and conversation, but also the main technical vocabulary, and a large measure of dialectical usage and slang.
