Oxford English Dictionary

The Oxford English Dictionary (OED) is widely regarded as the accepted authority on the English language. It is the most comprehensive record of the English language in the world with more than 600,000 words. 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 used for a particular concept or meaning over time.

The OED is updated quarterly.
