Are there any freely available dictionaries?

开发者_运维技巧I want to create dictionary for my iPhone application. For that I need a list of words with detailed meanings of the words in a database.

Can anyone suggest me a good word list that is freely available?

WordNet is indeed great, I used it in one of my apps with nice results.

WordNet's API requires some adaptation though - it doesn't come with an API for Objective-C, for example. That's why I made Lexicontext available as a static library - you might want to check it out too.

WordNet would be a fantastic place to start.

May be a good place to look.
