Just an update. Grammarly Pro can help you spot mistakes that normally you don't fiind with word….
BUT... the program doesn't necessarily recognize the difference between names you have already saved into word and what is in the database.

In fact, it often tells me for being too wordy which in some cases is okay. But when you are writing a book then this is a Problem

and it only does US English (And I think with a San Francisco dialect if you get my drift) because some of the suggestions from the program are bad

That being said once you understand the System it can be an invaluable tool
