We are releasing an updated version of the Khmer grammar checker for Open Office that includes a list of over 25,000 Khmer words tagged with parts of speech. This grammar checker is in the very early stages, so there are false positives, as well as rules we have yet to input. If you are interested in learning more go to the SBBIC Khmer grammar checker page here.
If you find an error, please add it to the comments. If you have a rule you would like to add, please let us know by commenting. Thank you!
