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