Maybe a linguistics expert can weigh in.
only hakka and sundanese ring a bell for the under 10% ones. Others I missed but definately recognise are amharic, punjabi, kurdish (i had tried kurdic among other things) and persian.
And I wonder which word triggered kinyarwanda. I got it right but sure didnt type that. Actually same with pastho and hmong,
Edit: looked it up, that would be afghani, I guess mong(olian) though that is not what it refers to. And rwandese
And never knew Sylheti and Chittagonian are that distinguished from bengali.
I think all "national" languages are on the location of the capitals of the countries.
