Grammar checking

There is no grammar checking function in OOo. There are, however, a number of grammar checkers under development:

Language Tool is a Python-based grammar checker originally written for German. Rules sets for Hungarian and English are also available. More information is available from http://tkltrans.sourceforge.net/ and from http://www.danielnaber.de/.

An Gramadóir is a Perl-based grammar checker originally written for Irish. More information is available from http://borel.slu.edu/gramadoir/index.html. [This one is probably the best suited for languages that use noun classes, or an evidential grammar.]

CoGrOO is a grammar checker for Portuguese that is still in the alpha stage. More information is available from http://www.pcs.usp.br/cgi-bin/jkinoshi/cogroo/experimente.cgi

Cymraeg is a grammar checker for Welsh. This is a commercial product. A demonstration copy of it can be obtained from http://www.bangor.ac.uk/ar/cb/cymraeg/demo_meddalwedd.php.
