Hunspell

Hunspell is a spell checker and morphological analyser designed for languages with rich morphology and complex word compounding and character encoding, originally designed for the Hungarian language.
Hunspell is based on MySpell and is backward-compatible with MySpell dictionaries. While MySpell uses a single-byte character encoding, Hunspell can use Unicode UTF-8-encoded dictionaries.
