I have seen a few posts about grammar lately and I wanted to bring up some archived posts which could be very helpful:https://community.wanikani.com/t/grammar-guide-1/6914?source_topic_id=19739
If you start here there are links to @GreenWarrior other grammar guides. You can also look up Green Warriors profile and go to them from there. They are really good guides and you can print them off and take them with you for studies on the go or in meetings.
Just wanted to leave this here as most of the posts are older and some people may not have seen them or remember them. Just know we miss @GreenWarrior and their amazing grammar skills. Take care all.
Side note: Sorry our thread got closed @darlingmud, maybe we can find time on another forum to have the discussion. Take care.
