Hunspell

Hunspell is a spell checker and morphological analyzer designed for languages with rich morphology and complex word compounding or character encoding, originally designed for the Hungarian language.

Hunspell is based on MySpell and is backward-compatible with MySpell dictionaries. While MySpell uses 8-bit ASCII character encoding, Hunspell can use Unicode UTF-8-encoded dictionaries.

Hunspell is the spell checker of:

• OpenOffice.org, a cross-platform office suite (starting with version 2.0.2 March 8, 2006)
• Mozilla products Thunderbird / Firefox (starting with version 3) and SeaMonkey (starting with version 2)
• WinShell, an integrated development environment (IDE) for TeX / LaTeX on Windows
• Yudit, a Unicode text editor for the X Window System
• Google Chrome, an open source web browser developed by Google.
• Moreover, Hunspell is supported by Enchant.

Hunspell is free software, distributed under the terms of a GPL/LGPL/MPL tri-license.
