Why is "Ñuhor ñāmar kirine issa" not accepted?
probably it just wasn't it the system at that time. but there's a mistake in your sentence: not "kirine", but "kirinior". with this correction it's accepted by now.
duolingo seems to nor recognize muna as a correct word for aunt (mother's sister)
That's been fixed.
Yeah she is ;) ;) Well, was..
