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 or translation, it will quickly shuttle you to the web-based dictionaries that define or translate that word. If you don't know how to spell the word, it will help you do that too. No word is too obscure: More than 5 million words in more than 900 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.

Translate words: Type a word into the search box and select "Find translations" to retrieve a list of dictionary web sites that have translations of that word into other languages.

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.)
