OneLook® Dictionary Search is a free service developed and maintained by Datamuse. It's been in continuous operation since 1996! Many people have contributed to OneLook over the years:

• OneLook's original indexing technology was invented in April, 1996 by Robert Ware of Englewood, Colorado, USA, and redesigned by Doug Beeferman in 2002.
• Our service would be meaningless (literally!) without the hard work of hundreds of dictionary providers on the Web.
• The content that appears in the "Quick Definitions" section of our results pages derives primarily from WordNet, a project of Princeton University [license info], and data from the U.S. Census Bureau. It also derives from the hundreds of user-submitted additions and corrections we've received over the years.
• The encyclopedia excerpts that appear on some of the results pages are from Wikipedia, a collaborative encyclopedia made available under the GNU Free Documentation License, and are used with permission.
• The customized logos you see on this site from time to time were designed by Twotone Studio of Toronto, Ontario, Canada.
