The Grammar sub category is for Japanese grammar. WaniKani doesn’t actually teach grammar, so I’m sure you have many questions. Ask them here, get them answered. Or, if you’re feeling like a plant from Shel Silverstein’s wacky mind, you can give your Japanese grammar knowledge out freely to all who want and need it.
Do I really have to keep writing these descriptions? You know the drill. Just stick to Japanese grammar in this category and everything will be fine.
The Grammar sub category is "public" in that content of this category can be found via outside search engines, even without a WaniKani account. Please don't post anything that you don't want the public to see associated with your WaniKani username.
