Grammar

Grammar checker A grammar checker, in computing terms, is a program, or part of a program, that attempts to verify written text for grammatical correctness. Grammar checkers are most often implemented as a feature of a larger program, such as a word processor, but are also available as stand-alone application that can be activated from within programs that work with editable text. The implementation of a grammar checker makes use of natural language processing. History[edit] The earliest “grammar checkers” were basically programs that checked for punctuation and style inconsistencies, rather than finding many actual grammatical errors. Aspen Software of Albuquerque, NM, released the earliest version of a diction and style checker for personal computers, Grammatik, in 1981. Other early diction and style checking programs included Punctuation & Style, Correct Grammar, and RightWriter. Until 1992, grammar checkers were sold as add-on programs. Technical issues[edit] True grammar checking is more complex.
