Open source spell check

Answer 1

I've used Hunspell for a few things, and I don't really have any horror stories with it. I've only used it with English (American) though, but it claims to work with other languages.

As for licensing, it offers a choice of GPL, LGPL, and MPL. If you don't like the MPL, you can always choose to use the LGPL.

Answer 3

As already mentioned Hunspell is a state of the art spell checker. It is the Open Office, Thunderbird, Firefox and Google Chrome spell checker. Ports to all mayjo programming languages are available. It works with the Open Office Directories, so a lot of languages are supported.
