When Apple developed "a system-wide spelling checker" for Mac OS X so that "the operating system took over spelling fixes," it was a first: one "didn't have to maintain a separate spelling checker for each" program.

Although the size of the word-processing market in a country like Iceland might not have justified the investment of implementing a spell checker, companies like WordPerfect nonetheless strove to localize their software for as many national markets as possible as part of their global marketing strategy. However, this required increasing sophistication in the morphology routines of the software, particularly with regard to heavily- agglutinative languages like Hungarian and Finnish. However, the market for standalone packages was short-lived, as by the mid-1980s developers of popular word-processing packages like WordStar and WordPerfect had incorporated spell checkers in their packages, mostly licensed from the above companies, who quickly expanded support from just English to many European and eventually even Asian languages. On the pre-Windows PCs, these spell checkers were standalone programs, many of which could be run in TSR mode from within word-processing packages on PCs with sufficient memory. Developers such as Maria Mariani and Random House rushed OEM packages or end-user products into the rapidly expanding software market. The first spell checkers for personal computers appeared in 1980, such as "WordCheck" for Commodore systems which was released in late 1980 in time for advertisements to go to print in January 1981.

Henry Kučera invented one for the VAX machines of Digital Equipment Corp in 1981. A group of six linguists from Georgetown University developed the first spell-check system for the IBM corporation. The first spell checkers were widely available on mainframe computers in the late 1970s. SPELL, its algorithms and data structures inspired the Unix ispell program. Gorin made SPELL publicly accessible, as was done with most SAIL (Stanford Artificial Intelligence Laboratory) programs, and it soon spread around the world via the new ARPAnet, about ten years before personal computers came into general use. Gorin wrote SPELL in assembly language, for faster action he made the first spelling corrector by searching the word list for plausible correct spellings that differ by a single letter or adjacent letter transpositions and presenting them to the user. Ralph Gorin, a graduate student under Earnest at the time, created the first true spelling checker program written as an applications program (rather than research) for general English text: SPELL for the DEC PDP-10 at Stanford University's Artificial Intelligence Laboratory, in February 1971. In 1961, Les Earnest, who headed the research on this budding technology, saw it necessary to include the first spell checker that accessed a list of 10,000 acceptable words. In some cases, spell checkers use a fixed list of misspellings and suggestions for those misspellings this less flexible approach is often used in paper-based correction methods, such as the see also entries of encyclopedias.Ĭlustering algorithms have also been used for spell checking combined with phonetic information. Key advantages include needing less runtime storage and the ability to correct errors in words that are not included in a dictionary. This approach usually requires a lot of effort to obtain sufficient statistical information. An alternative type of spell checker uses solely statistical information, such as n-grams, to recognize errors instead of correctly-spelled words. Spell checkers can use approximate string matching algorithms such as Levenshtein distance to find correct spellings of misspelled words.

It is unclear whether morphological analysis-allowing for many forms of a word depending on its grammatical role-provides a significant benefit for English, though its benefits for highly synthetic languages such as German, Hungarian, or Turkish are clear.Īs an adjunct to these components, the program's user interface allows users to approve or reject replacements and modify the program's operation.

For many other languages, such as those featuring agglutination and more complex declension and conjugation, this part of the process is more complicated. Even for a lightly inflected language like English, the spell checker will need to consider different forms of the same word, such as plurals, verbal forms, contractions, and possessives.
