Likely the preeminent source for definitions of words in the contemporary American English language. Orginally based on the landmark Webster's Third New International Dictionary of the English Language, but in a constant state of revision and updating, with fascinating features on new meanings and popular searches.
The OED is the accepted authority on the history of words in the English language. It is the most important guide to the meaning and history of over a half-million words, both past and present, tracing the meanings of these words through the use of over 2.5 million quotations, drawn from a wide range of sources. Quarterly updates include at least 1,000 new and revised entries. The W&L library also has printed copies of the 1st and 2nd editions.
Searching Use the basic "Quick Search" option to find entries featuring a particular word or multi-word term. Results will be arranged by parts of speech (noun, verb, etc.) Please note that each individual resulting entry is displayed in a brief "Outline" form; to view the more complete entry, click on "Full entry," above the definition(s).
The "Advanced Search" option (beneath the search box) can be useful when you are searching for a particular meaning or connotation of a word. Example: Enter the gay as a "Headword" and the word homosexual in "Full Text" (or "Definition").
The Historical Thesaurus feature enables you to research "words associated with a given idea."
The Dictionary of American Regional English (DARE) is a multi-volume reference work that documents words, phrases, and pronunciations that vary from one place to another place across the United States.
