I was browsing through an older book* of mine for review, and I noticed that in the chart they had for “may/permission” had additional formalities I hadn’t seen before. I was curious if such formalities are accepted as answers on Bunpro, or if they should be added as separate grammar points? (I don’t know what’s on the JLPT, and I don’t know if Bunpro cares to include things outside of it.)
May/Permission Chart: (as listed/categorized in the book)
Formal:
~てもよろしいです、てもかまいません、てもいいです
Informal:
~てもかまわない、てもいい
Colloquial:
~ていい
*For those curious, the book is “Japanese in Mangaland 2” but it’s not one I’d recommend for beginners. It’s more of a review book.
