молния

• мо́лнія (mólnija) — Pre-reform orthography (1918)

Inherited from Old East Slavic мълниꙗ (mŭlnija), мълнии (mŭlnii), from Proto-Slavic *mъlnьji[1] or *mьlnьji,[1] from earlier *mъldnьji[1] or *mъldni,[2] from Proto-Balto-Slavic *mild-n-, from Proto-Indo-European *ml̥dʰ-n- (“lightning”).

Slavic cognates include Serbo-Croatian муња (munja), Bulgarian мълния (mǎlnija), Polabian måuńa and Kashubian môłniô. Probable cognates outside Slavic include Latvian milna (“hammer of Pērkons”), Old Prussian mealde, Welsh mellt (“lightning”), Old Norse Mjǫllnir (“hammer of Thor”).
