  • Welcome to OneLook® Dictionary Search

    Think of this web site as a search engine for words and phrases: If you have a word for which you'd like a definition, we'll quickly shuttle you to the web-based dictionaries that define that word. If you don't know the right word to use, we'll help you find it. No word is too obscure: More than 19 million words in more than 1000 online dictionaries are indexed by the OneLook® search engine.

    What can you do at OneLook.com?
    • Define words: Type a word into the search box on the front page to retrieve a list of dictionary web sites that define that word. Be sure "Find definitions" is selected.
    • Find words: Type a pattern consisting of letters and the wildcards * and ? to retrieve a list of words matching your pattern. The asterisk (*) matches any number of letters or symbols. The question mark (?) matches exactly one letter or symbol. (More info on wildcards and the Reverse Dictionary.)
    You can explore the other links above this box for more information on OneLook.com. (Don't forget to check out our cool customization features!) Please read our FAQ or send us feedback if you have any questions. When you're ready to try it out, simply return to the front page.
