The Shanyagir had a word for thunder but not for lightning?

Who knows? I suppose that Chuchan of the Shanyagir tribe spoke some sort of Tungusic language, but was speaking with I M Suslov in Russian or being translated for him by some bilingual person. Russian does distinguish between lightning (молния molnija, related to the Old Norse word for Thor's hammer mjo̧llnir) and thunder (гром grom). It is interesting that in English bolt of lightning can also be called a thunderbolt (удар молнии udar molnij 'thunder strike, blow').
