Editing Spell checker (section)

===Unix===

The [[Ispell|International Ispell]] program commonly used in Unix is based on R. E. Gorin's SPELL. It was converted to C by Pace Willisson at MIT.<ref>{{Cite web |title=International Ispell |url=https://www.cs.hmc.edu/~geoff/ispell.html |access-date=2023-02-19 |website=www.cs.hmc.edu}}</ref>

The GNU project has its spell checker [[GNU Aspell]]. Aspell's main improvement is that it can more accurately suggest correct alternatives for misspelled English words.<ref>{{Cite web |title=GNU Aspell |url=http://aspell.net/ |access-date=2023-02-19 |website=aspell.net}}</ref>

Due to the inability of traditional spell checkers to check words in complex inflected languages, Hungarian László Németh developed [[Hunspell]], a spell checker that supports [[agglutinative language]]s and complex compound words. Hunspell also uses Unicode in its dictionaries.<ref>{{Cite web |title=Hunspell: About |url=https://hunspell.github.io/ |access-date=2023-02-19 |website=hunspell.github.io}}</ref>
Hunspell replaced the previous [[MySpell]] in [[OpenOffice.org]] in version 2.0.2.

[[Enchant (software)|Enchant]] is another general spell checker, derived from [[AbiWord]]. Its goal is to combine programs supporting different languages such as Aspell, Hunspell, Nuspell, Hspell (Hebrew), Voikko (Finnish), Zemberek (Turkish) and AppleSpell under one interface.<ref>{{Citation |title=AbiWord/enchant |date=2023-02-13 |url=https://github.com/AbiWord/enchant |publisher=AbiWord |access-date=2023-02-19}}</ref>
