How can I use the Word grammar checker with my macro?

I am trying to use the Word grammar checker in my documents but I would like to know if its possible to edit the grammar checker to, along checking the grammar, it will also use my code.

My code basically checks for certain words that are NOT to be used in the document.

I am basically trying to build a tool that will help people write bullet proof requirements. This tool will scan the whole document and search for the words that can NOT be used or are NOT allowed to be used within requirements. It can do that so far. But now I want to also use the Word grammar checker so that it can identify the subject, verb, noun, adjective etc....

I dont know where to start?

anyone?
